After more than three decades of teaching at Jemicy, I thought I’d pretty much seen it all. Enter Spring, 2020. The coronavirus completely upended any semblance of normalcy as we pivoted abruptly to teaching online. It seemed impossible that we could maneuver our way through the thick tangle of COVID restrictions and concerns of families and staff to actually reopen this fall. But here we are, restructured into smaller, isolated groups -“neighborhoods” – each with its own dedicated spaces and faculty. And, in a strange twist, one of my long-held dreams has finally come true: getting to teach entirely outside.

My science classes have always seen plenty of outdoor time, but this is different. This year I am intentionally restructuring the curriculum to prioritize and fit outdoor spaces – those places that I have always described as the biggest, best classroom in the world.

The JE neighborhood started getting to know their larger neighborhood by asking, “Where in the world are we?” We mapped our campus, walking the perimeter through weeds and woods, along streets and streams. Our moose mascot (who wears a mask and also a cool spiderweb beard), situated at the top of our front circle, conveniently aims north. It became the reference point for orienting ourselves wherever we happened to be. We identified notable landmarks (“Does a pile of deer poop count?”) and topographical features while adding to our biodiversity checklist.

Screen tents, the outdoor pavilion, and any place where we could find some distance, sit or place a yoga mat, became gathering spots. Along with lessons on animal classification, adaptations, and seasonal changes, we coordinated science and art classes to study the distinct characteristics and beauty of the leaves that surrounded our outdoor neighborhood.

Class time was also regularly devoted to letting kids play in the woods and develop their own unique communities there. We took trips to Jemicy’s bamboo forest where we harvested poles for fort construction. A new barter system quickly developed: “I’ll trade you this part with leaves for that short, fat stick.” “Will anybody trade me one long bamboo for two bricks?”

Friends found ways to help each other while staying safely at a distance. A giant beetle larva was unearthed during stone collecting, admired, and safely replaced. Burdock plants dispersed their seeds by using unwitting mammal “fur,” much to the mammals’ annoyance. Adopted tree seedlings found permanent homes.

What will happen when the weather turns cold? We had a taste of that this week as we gathered in the pavilion, shivering, with temperatures in the 40’s. Conveniently, our topics were seasonal endothermic (warm-blooded) and ectothermic (cold-blooded) animal adaptations. Kids immediately gravitated to the sunnier side of the structure, jumped up and down, and ran laps to get warm. “It’s probably too cold to bring the snakes out here, isn’t it?” asked one wistfully. “But maybe the guinea pigs?” We observed crickets, how their behavior changed when we moved them from shade to sun, then released them to find their way to winter accommodations.

Finally, we pulled on our boots and headed to the woods, where the kids took one look at the deep, shaded stream valley and predicted that the water would be too cold for frogs. A fresh shed from a snake confirmed that some cold-blooded creatures were still conducting business as usual.

We did find a couple of spunky young frogs that were still actively elusive in spite of the season officially shifting from summer to fall. Fortunately, it was also too cold for the mosquitoes that had plagued our previous hikes.

I stopped by yesterday to tour a set of forts that several girls were working on, noting that while they had followed this year’s new guidelines not to share close spaces, they had left open passageways from one fort to another. They gave me a tour of newly installed seating, decorations, and the hollow bamboo tube where visitors could put their “money” (large green fruits) for admission. “The money grows on that bush,” they said, pointing out their nearby revenue source, “so really anybody can come in with permission.” And when I asked about their open concept layout, they responded, “Well, we didn’t want to just build forts – we wanted to make a neighborhood!”

Skipper song


When Jemicy decided against having camp this summer due to the pandemic, I found myself searching for a new personal learning opportunity, preferably one that would keep me outdoors as much as possible. An online butterfly class caught my eye, and soon I was enrolled in a seminar that is traditionally field-based and taught in Vermont, but that fortunately expanded this year to include students from around the country. What especially attracted me, beyond the chance to spend hours in the field, was the use of photography and an iNaturalist project for sharing images and helping each other identify species.

Bryan, the instructor, asked about our individual goals for the course. “Skippers,” I answered, though not without misgivings.  Referencing a birding term for a group of species whose similar appearance presents aggravating identification difficulty in the field, skippers are known as the “sparrows” of the butterfly world. Hesperiidae is a family of relatively small, often drab-colored butterflies that people sometimes mistake for day-flying moths. They have a plump thorax and large eyes, hooked clubs at the end of their antennae, and a characteristically darting flight.

For years, in spite of their prevalence, I had mostly avoided getting to know these tiny, triangular enigmas. Only a few in this region, like the silver-spotted skipper, are sizable, distinctly marked, and readily identifiable at a distance.

Silver-spotted skipper

There just didn’t seem to be a way to reliably distinguish one little orange-brown speck from another.  “At least sparrows have distinctive songs,” I sighed. But learning skippers, I decided, was a worthy summer challenge. And a good excuse to spend time in some of my favorite places, searching for and photographing a few of the 150 or so butterfly species found in Maryland.

From mid-June through July, I scoured the local parks and trails with a singular focus, finding new appreciation for the beauty of butterflies that I knew well and relishing the surprise of new discoveries. This rather worn, brown butterfly that I was about to dismiss as the ubiquitous little wood satyr? No, wait, there was something different about those spots and how it was flying. Turns out it was an Appalachian brown, a not uncommon species, but one new to me.

Appalachian brown

The urge to find new butterflies pulled me out of my immediate neighborhood a few times. Remembering a butterfly spotted a year ago at a distant park, I headed there again. Along the same edge of the same field in the same 90 degree heat, a flash of orange in the grass caught my eye – a silvery crescent nectaring on a dandelion, possibly a descendant of last year’s butterfly.

Silvery crescent

Another time, using the filters on iNaturalist to see where other people were finding certain species, I drove down to the Patuxent Research Refuge. Not only was I rewarded with zebra swallowtails in abundance, but I finally got to see the resident pair of trumpeter swans – two first sightings!

As the weeks went by and my vocabulary of butterfly characteristics expanded, it took little more than a glance to recognize and mentally note the low, flat glide of a buckeye, the frenetic dance of an eastern tailed blue, the bounce of a common wood nymph. I often paused not to capture, but to simply enjoy the show: an eastern tiger swallowtail uncurling its long proboscis, a red admiral slowly spreading its red-banded wings to the sun and then snapping them shut to reveal the incredible intricacy of their ventral pattern.

All this time, the skippers were darting about, teasing my ability to recognize them. Perched at one angle, a skipper could be a swarthy – at another, a dun. Field marks disappeared under both the sun’s harsh light and in dappled shade, and I tried every camera setting I could think of to capture something – anything – that would answer the nagging question, “Who ARE you? Sing to me!”


I read up on voltinism, or the different broods and flights of a species which caused them to show up in numbers, freshly emerged, for a week or two and then  disappear. Little glassywings took over entire fields from the previously abundant but now abruptly vanishing zabulon skippers, only to disappear themselves after a few weeks, replaced by a fresh flight of Peck’s skippers and sachems. Meanwhile, there were the reliable constants: diminutive least skippers bobbing in and out of the grass in wetter places, and bold silver-spotted skippers that seemed to enjoy nothing better than zooming into a milkweed plant to spoil my shot of a monarch or great spangled fritillary.

The skippers flitted about and displayed their nature in ways that were at first incomprehensible. I had to learn which field marks were critical to note and photograph. Was it the ventral side? Dorsal? Under the head? Complicating matters were the differences between male and female of the same species, between freshly emerged and worn individuals, between an early brood and a later one. Some days I would return home with multiple images of the same skipper, try to identify it with a field guide, and then turn to iNaturalist for suggestions, only to have the app give me 3 or 4 different IDs. Obviously I was missing some essential characteristic – but which?


In mid-July, the unrelenting heat and voracious ticks forced me into a 10-day hiatus from butterflies. I worked on indoor projects, preparing for school’s imminent reopening, and tried to let images of all the butterflies I was missing settle into memory. Sometimes while taking the dog for a walk, a shadow would waft overhead, or a tiny orange shape would dart past my ankles and disappear in tall grass.  The way that shadow seemed to simply float past – likely a swallowtail. The size, shape, and pattern of that skipper – probably a Peck’s. Not having a camera or binoculars along allowed me to simply observe, to appreciate subtle differences in behavior – how the butterfly moved, what kinds of plants it was using, whether it returned to the spot where I had disturbed it or was gone for good, how it interacted with other insects.

Eventually I was ready to return to hiking, whereupon I found a whole new community of butterflies hard at work nectaring, mating, laying eggs, avoiding predators.

Many were newly emerged individuals of species I had seen earlier in the summer. The skippers flitted between flowers, landed and nectared, scared each other off and sometimes simply held a pose, allowing me to approach within inches. Their identities occurred to me now more intuitively as I watched them in context, picking up a range of clues. That’s when I realized that skippers do, indeed, have a song. Not in an acoustic sense, but as a suite of qualities that included time, location, weather, behavior, relative size and shape and – for lack of a better word – personality. Bryan, who had spent much of the course assuring us that we would eventually get to the point of really knowing these creatures, captured the essence of a butterfly’s personality in his recent blog post on the mulberrywing skipper. It’s a species that I will likely never see in my neighborhood, but I am certain that his description of its “song” will allow instant recognition if I ever encounter it.

Having logged over 200 observations of 40+ butterfly species on iNaturalist, I find my motivation for learning has only increased. So, I’m already starting to think about next summer: Who are the sparrows of the dragonfly world, and what is their song?








Spring surprises

Along with everyone else facing the COVID-19 threat, I have spent a lot of time trying to both deter and prepare for the possible arrival of the virus in my home. My efforts to delay this visitation through distancing and staying home have become second nature, but the expectation itself diverts energy and attention to something ominous that lurks unseen and intangible.

And yet it’s spring, the best possible antidote that I can imagine to this wearisome watchfulness. Though wet and cold (a polar vortex is paying an unseasonable visit at this very moment) this spring has delivered some welcome surprises. One of my favorite parts of Jemicy’s online learning program is that my students and I have been sharing our nature observations, along with the excitement that comes with new discoveries and phenomena that capture our attention. Nature-related stories fill much of our live class meetings and often feature a child exclaiming, “Here – let me show you!” and taking the class along on her iPad to see the nest in her porch planter, a flower blooming, or a tree frog tucked under an edge of siding. Below are just a few of the photos students have shared from their homes and backyards.

Squirrel rescue, nests tucked into mailboxes and garage corners, eggs and hatchlings in many stages of development.

Strange rocks and lichens, animals showing up unexpectedly.

Flowers and trees with new leaves.

Gardening, birding on a bike, exploring streams. 

And, one of my favorites: a slug drawing with slime.

Screen Shot 2020-05-09 at 7.05.15 AM


For the first time since I’ve lived here, I’ve heard whippoorwills at dawn, seen an osprey carrying a fish to its nest, watched a wet raven preen and announce its presence at the top of a dead tree.


I’ve seen butterflies, fungi, birds, insects, and wildflowers that I knew lived here but had never before found or had the chance to photograph.


Each of these encounters – both mine and my students’ – feels like a gift from a world of biodiversity that still provides a safe haven for wonder.





Bringing biodiversity home, literally

When I was a child somewhere in those wondrous years between 7 and 10, I was a voracious animal collector. Springtime brought a wealth of opportunities to find frog eggs, red-spotted newts and rat snakes, to set up an ant farm in a peanut butter jar, to capture a mouse and house it in a hastily constructed cage, only to find it gone in the morning. My enthusiasm was fueled by a book whose words and images were so enticing, so perfectly attuned to my passion that I memorized every page and could never part with it: “The Golden Book of Wild Animal Pets.”

When I look through this book now, I am deeply thankful that I was not a very skillful or ruthless hunter. The animals that I did manage to capture invariably led short, miserable lives. And it wasn’t just wild animals. If a stray dog or cat showed up on our property, I would try to hide it in the barn in a kennel made of hay bales, sneaking food from the house. This rarely worked out in any creature’s best interest. One day I made a surreptitious trade of some unused toy for a neighbor’s rabbit, but this time when my mother discovered it, she agreed to let me keep it if I would build it a proper hutch and clean it regularly. “Someday,” I promised, “I will have my own house where I can keep all the animals.”

Little did I know that the title of this blog would fulfill that promise quite literally this week as our school closed due to the coronavirus pandemic. Not knowing how long we would be away, I knew that the school menagerie would be coming home with me. Now installed in the guest room, the various cages and tanks house animals that have been at Jemicy anywhere from 30 years (Blotch, the ball python) to the imminent (incubating chicken eggs due to hatch in three weeks). Since I will be teaching my students online here for the foreseeable future, the animals will play virtually the role that they always have in our classroom: species ambassadors helping to impart knowledge and insight into the lives of others.IMG_4893

On the other hand, the COVID-19 coronavirus itself represents a piece of the world’s biodiversity that I am making every effort to NOT bring home. In trying to understand the nature of recent epidemics and pandemics with apparent non-human animal sources, I came across a recent article from Scientific American that highlights this issue. Habitat destruction not only reduces biodiversity directly, but it can also open pathways for new pathogens to enter human spheres. Also benefiting from human incursions into formerly wild, remote areas is the exotic pet trade that results in animals such as the ones now inhabiting my guest room. My view of these beings has evolved from passion to compassion, and to demonstrating for my students what responsible pet ownership entails. It might mean a hurried evacuation. Or soaking a shedding snake in the bathtub.

I started this blog nearly five years ago as a way to share my learning and experiences during six months in Tasmania and New Zealand on a Fulbright award. Being so far removed from my Jemicy students, living on remote islands on the other side of the world, I treasured the online connections that we devised. Our present challenge is to make these same meaningful connections across distance that feels almost as vast, since we are all separated from each other, each in our own home. My goal this spring will be to use these separate home spaces as common ground for discovery and learning. We will be sharing observations of the nature around us, both in terms of living things and the physical environment, experimenting remotely, exploring our backyards, and discovering the heart of bringing biodiversity home.






January to February is a time that always seems to hold its breath, waiting for something to happen: Will it snow? Will there be a thaw? Will this bitter gray weather ever break? Unpredictability is a standard condition. January 29 is the average coldest day of the year with temperatures at 30 degrees F. However, the typical range from 30-43 degrees has enough variability to induce buds to blossom and amphibians to seek breeding ponds. Once these actions are set in motion, there’s no turning back, no matter what the weather has in store. 17038792_1342428442501317_7254892838485278669_o

It is the best time of year to find those things outdoors that are waiting to change, or have already begun the process. Moth cocoons, praying mantis oothecae (egg cases), beetle pupae, seeds, tree buds, slug eggs  – they persevere through whatever weather conditions come their way, holding new life in reserve until the moment is right.


In our visitor tank in the science room, we are closely monitoring some of these. A fat green caterpillar that we had intended to observe only briefly late this fall, and then return to the outdoors, surprised us by quickly cocooning itself to the side of the tank. We decided to leave it to see if and when the adult would emerge. An introduced species of praying mantis also spent the fall in the tank, dined on ever-plentiful crickets and stinkbugs, and left us with an ootheca. There is a matching one waiting outside on a nearby shrub.


The youngest JE’ers spent a class this fall roaming the campus collecting dried seed heads from a variety of flowers: marigolds, joe-pye weed, milkweed, black-eyed Susan, coneflower. These are waiting for a later class in February, when we will start seed trays for the gardens around the science building.

And, in the top garden bed are a dozen tree seedlings – holly, tulip tree, pawpaw, and hickory – awaiting transplant to their new home in the reforestation area. Their buds are still dormant, but just a few feet away the buds on the dwarf peach are swollen, looking impatient to blossom. We hope it can wait just a bit longer, because there is really no telling what February has in store for us.



Seasonal instincts

As earth moves ever closer to its annual winter solstice, inhabitants of Jemicy’s science building take notice. The sun’s lower angle sends the afternoon rays more directly through the greenhouse bay and onto the glass walls of the fish tank, causing algae to proliferate and algae eaters to become more active. Meanwhile, that same shift in angle and lower daily temperatures send many of the classroom reptiles into a state of semi-hibernation, or brumation. The Russian tortoises stop eating, dig down into their bedding, and only reluctantly reawaken for occasional hydration. The male corn snakes have also stopped eating and moved to the cold end of their enclosure, where they will curl up together and remain nearly motionless for the next five months.

Time has taught us that these are normal seasonal behaviors reflecting what these animals would do in the wild. Even though the reptiles’ enclosures have heat and UV lamps, they somehow know what is going on outside and are responding to those external cues. Just last week we discovered a tiny, disoriented spring peeper in a classroom, the first one we’ve ever found as late as December. The temperature outside was in the 40’s, and we knew it was bound to get much colder soon, but we released the frog to the woods confident that it would find its way to a safe hibernaculum for the next few months.


Last month, JE students who were studying cold-blooded animals created their own “herps” to model hibernation out in the Jemicy woods. We drew animal figures on gloves, filled them with colored “blood,” and carefully hid them in places where we thought no predators would disturb them. These herps will wait out the winter as still and silent as the living frogs and salamanders that have burrowed themselves down under logs and into the mud of the stream bed nearby. When spring returns, we will see how they have fared, whether their skin remains intact, or whether some gnawing rodent has unfortunately discovered them.

As a strategy for surviving winter, entering a state of dormancy seems risky to those of us adapted to staying active, but it works for a variety of animal groups, and not just herps. In Maryland, black bears, groundhogs, and bats seek burrows or other shelter to sleep away the cold winter months. A recent article on hibernating bats illustrated a unique use of snow dens for chilling out in winter.

What about those animals that use migration as a means of surviving winter? To better understand the incredible sense of direction demonstrated by birds, butterflies, dragonflies, and other migrating creatures, the JE classes explored magnetism.

We made floating compasses with magnetized needles,

drew treasure maps to practice compass directions,

and practiced orienting ourselves outdoors using the sun and other natural clues.IMG_3857

It is hard to grasp how other animals instinctively find their way to distant destinations, just as it is difficult to imagine being drawn into a long period of dormancy. For humans, we decided, the most elemental attraction in the cold of winter is a warm campfire. With marshmallows.campfire

Water works

“A significant lack of recent rain, and unusual heat during the month of September, led to the development of what is called “flash drought” across a large portion of the area. This essentially means that the short-term dryness and heat quickly overcame the long-term record wetness we experienced between April 2018 and the early summer of 2019. Although the heat has ended, significant rain has not yet been observed, so drought conditions persist.”  National Weather Service, October 8, 2019


If you live along the East Coast, chances are you noticed how dry it was in late summer and early fall, though this “flash drought” came as somewhat of a surprise after the extended sogginess of the previous year. Given the vital role that water plays in the lives of all living things, and its effects on non-living ecosystem components as well, the JE classes embarked on an intensive study of the many characteristics that make water so central to our lives.

We began by learning about physical and chemical properties of water. Positive, neutral, and negative buoyancy were introduced using numerous objects, and by learning to make and test reasonable predictions. Classifying objects by their float-ability was more challenging than many expected.

Experimenting with different densities and surface areas enabled more accurate generalizations, and we followed this with the classic penny boat challenge: “How many Abraham Lincolns can you keep afloat on your foil boat?” Results ranged from 0 to an astounding 200+. The cardboard boats that followed used wind power to move across our mini-ocean and featured creative detailing that tested the boats’ balance and waterproofing.

Having seen negative (sinking) and positive (floating) buoyancy in action, we attempted to achieve neutral buoyancy (within the water column). Our rock/balloon constructions mimicked fish and submarines with swim bladders and ballast tanks, with success dependent on finding just the right balance.

Next, it was time to review water’s different states of matter: solid, liquid, and gas. We enacted the difference in energy between these three states by playing a tag game where kids responded to a shouted prompt by finding others to quickly form an unmoving solid or flowing liquid, or by running away as a gas molecule. We also had fun trying to predict liquid capacity in different containers and playing with dry ice reactions.

Our typical introduction to the water cycle involves learning big words with big movements. Students jump off the classroom tables while shouting “Precipitation!”, “Runoff!” to the corners of the room, “Evaporation!” while climbing back onto the tables, and “Condensation!” while huddling together as cloud vapor.IMG_3224

This year, we added a technology component: augmented reality in the form of a MergeCube. This cool tool pairs with an iPad to create 3-dimensional views of all sorts of science content. For this lesson, we were able to make each stage of the water cycle play out in a miniature world complete with water raining onto and running off a mountain into streams and a lake, and then evaporating into wispy clouds. We reinforced these images with one more game, creating large cardboard dice showing different parts of the water cycle and designing multi-player game boards.

Throughout these water-based activities, we talked often of the lack of rain and how it might be affecting our campus. The small stream in the woods, which has its source in groundwater seeps, has sometimes dried up during extended droughts. This year it persisted throughout the fall, though with diminishing flow. Frogs, crayfish, and salamanders were found in the deeper pockets, but the vegetation along the banks hung limp and pale, lacking its usual fall vibrancy.

“Where is this water still coming from, if there’s no rain?” we wondered. The NWS report indicated that, in spite of the drought, deep groundwater remained at relatively normal levels, which apparently continued to supply us with enough water to keep the stream flowing. By October 15, however, still with no rain in sight, our region’s drought status had changed to severe. Groundwater levels were dropping.

A week later, relief arrived in the form of several days of drizzle and occasional heavy rainfall. The air along the newly recharged stream is pungent now and “finally smells like fall,” one frog hunter declared as he studied the current.090319-15

Our final water topic currently underway is a study of fish adaptations for underwater life. Given the erratic nature of our weather patterns this fall, and the tendency toward more extreme weather events and water quality impact as our climate warms, the challenge will be to design fish with adaptations to survive such changes. Mudskippers may once again have their moment.

What are the animals for?

During a recent Back-to-School night, parents gathered in the science building to hear how their children would be spending their time in science classes this year. After my introduction, a parent raised her hand. “What will you be using the animals for?” I scanned the room, taking in the dozen or so habitats housing snakes, guinea pigs, a poison dart frog, fish, zebra finches…IMG_2621A simple question with a multifaceted answer. Very few classrooms feature so much biodiversity, at least of the vertebrate kind. Yet each of these animals, rescued or donated by families who could no longer keep their pet, plays an important role as an ambassador for its species. Each displays characteristics that help children understand it not just as an individual, but as representing a lineage distinct from humans and each other. Animals are also attention magnets, capable of capturing and holding a child’s focus while delivering immediate multisensory reinforcement of concepts that are being taught. This space is a “companionable zoo” where animals are partners in the learning process.

In last week’s JE classes, our older Russian tortoise, Borise, took center stage. As the students sketched her, she wandered around the table, occasionally meandering onto one of the kids’ dry-erase boards. “Hey! She likes me! She likes the drawing I did of her!” they would shout. Eventually, the focus became whose work Borise liked best, as evidenced by her movement toward a particular sketch.

Was the tortoise really paying attention to the drawings? What other variable could entice her to choose one direction over another?  Food? Light? Shelter? These are things that we can and will test, with respectful, humane, and scientific methods, setting in motion an increasingly sophisticated inquiry process over students’ years at Jemicy and beyond. Employing our easily observable (and yes, endearing) classroom animals as demonstrators of specialized adaptations enlarges our perspective on the experience of non-human others. How are they like us? How are they different? Why do they display these differences?

M Group’s first science research project identifies some of these key characteristics of our classroom animals. Each student chooses an animal to observe, while also researching the natural history of its species in the wild. Every year there are eye-opening discoveries that lead to critical discussions about research methods, physiology, cultural differences, the pet trade, reproduction, climate, etc.

  • “It says that ball pythons only live about 10 years in the wild, but 30 years in captivity. Does that mean Blotch set a new record? And how do they know how long they live in the wild?”
  • “Oh NO! They EAT guinea pigs in South America?!”
  • “All the Chilean tarantulas I see online are very hairy. Why is Sponge Bob bald?”M animals-9
  • “If it’s called a poison dart frog, why isn’t Blue poisonous? And if he’s not poisonous, why can’t I hold him?”IMG_2624 (1)
  • “Why can’t I find any pictures of molly fish eggs?”IMG_2625
  • “The chinchilla is so soft, it’s like you can’t even feel her fur! But why won’t she let us hold her?”M animals-3

Every day, the younger JE groups spend part of their class time with a particular animal, learning about its adaptations and accompanying vocabulary. Did you know that some snakes have vestigial legs? That a tortoise cannot crawl out of its carapace and plastron? That a gecko’s tail can regenerate? That snakes have no eyelids, and they shed the “brille” that covers their eyes? That guinea pigs are coprophagic?

Sometimes we are able to hold or touch an animal, and sometimes not. An often-repeated phrase: “It’s not about what you want. It’s about what they need.”  A snake that is hungry, a chinchilla that needs her space, a bird that will always view us as predators, a bearded dragon in defensive “blue beard” or “pancake” mode: these are all animals whose behavioral response to humans we learn to identify and respect.

How to convey the significance of animals to parents in such a brief moment? I may have said, “The animals support what we teach and the importance of respecting others.” What I hope this really means is that their continued presence in our classroom will engender not only a scientific but also a humane approach to interacting with diverse creatures that are wholly dependent upon us for survival.gp2


Late bloomers

In spring and summer as I’m tending my gardens at home and at school, I click into keep/discard mode. It’s usually pretty straightforward: keep what I planted, discard the rest. But inevitably I pause at the same spot every year, stymied: What is this rangy, tough-stemmed plant that’s pushing upward with such determination? I’m sure I didn’t plant it. A friend wanders by, sees me studying it, and offers an opinion. “A weed, for sure.” I’m not so sure. There are no visible flower buds, nothing that promises to enhance summer’s blossoming and entice insects and hummingbirds. Just some thin, jagged leaves, a reddish stem, and a branching pattern that suggests…something. Something that convinces me to let it be, to wait and see.Eupatorium serotinum

I’m glad I did. The plant that I decided to ignore all summer just waited as the sunflowers, coneflowers, and black-eyed Susans burst into bloom, flashed their gaudy petals (or were eaten by the deer), and then became food for the finches. Finally, as I was contemplating spreading compost and putting the beds to bed for the winter, I noticed it. Actually, what caught my eye first were its visitors: sulphurs, monarchs, skippers, buckeyes, wasps, bees, ants.

A stunning array of insects worked over the inconspicuous, delicate white flower heads. I hardly knew where to look first, much less how to focus my camera lens to capture the abundance. Only then did the identity of the plant finally enter my consciousness: late boneset, also known as late thoroughwort. Eupatorium serotinum. Pollinator magnet.

This is not the only “weed” that waits until late summer to attract pollinators. Goldenrod, aster, ironweed, blazing star, and a host of other plants welcome visitors through September and into October in this region. Why so late? Many late-season pollinator species overwinter as larvae or use the nectar derived from fall flowers to fuel migration southward.

E. serotinum won’t be forgotten next year. I’ve submitted photos to the Maryland Plant Atlas, which has no formal record of it for either the Cockeysville (Jemicy LMS) or Reisterstown (my house) quad, in spite of its ubiquity. Better late than never!



Can’t make (some of) this stuff up

The JE science classes focused on insects this spring, studying the life cycles of cockroaches, mealworms, silkworms, and other 6-leggeds. Their final project was to create a unique insect species in suitable habitat, depict its life cycle stages, and tell a story about an adventure that it had.



The invented insects were fantastically diverse, both morphologically (though they did follow “insect rules” with 3 body parts and 6 legs) and in their adaptations to their living conditions. In response to the questions, “What do you eat?” and “How do you keep from being eaten?” responses ranged from blood-thirsty  – “It can and will eat every other insect” – to benevolent – “Does it have to be a predator? This insect just wants friends.”



What struck me was that in the description of every seemingly invented insect, there was more than a hint of reality. Insects can be voracious and indiscriminate predators (praying mantis). They can also display behavior that we might encourage students to emulate: cooperation and care for young (social insects), and dogged determination (dung beetle). But frequently insects interact with their environment in ways that are just… bizarre.

  • One damp morning I was crossing a side street near my house when I saw what looked from a distance like a snake, and judging by its ragged shape maybe one that had been hit by a car. But there was movement, too, an undulating forward motion. It was only when I got within a few feet that I could see that the creature was actually hundreds of larvae woven together like rope fibers, moving determinedly as one toward the opposite side of the road. A few had lost contact and dropped off the back, but they were still aiming in the same direction as the mass of their fellow larvae.


This, it turns out, is the preferred migration method of dark-winged fungus gnat larvae.

  • Down in the woods during recess one day, someone pointed to a large, colorful, spidery insect repeatedly appearing to sting a rotting log.

I knew this must be a female of some species laying eggs, but I assumed it was one of the ichneumon wasps that has the uncanny ability to deposit eggs through its mammoth ovipositor into rotting wood directly over the tunneling larvae of its favorite beetle prey. The eggs hatch, and lunch is served.


This new insect, however, turned out to be a fly – a cranefly that lays its eggs in the dead wood that its larvae will later feed on.

  • On one of our many searches for new insects in the milkweed patch, a student pointed to a minuscule gold dot on a leaf. “Is this something new?” I could barely see the bug, but I dutifully took a picture, and when I enlarged it, saw that it was an aphid.

Or was it? Turns out, it was an aphid mummy: the skin of an aphid hosting the parasitic larva of a braconid wasp.

  • Another day, a tiny, dance fly perched on a leaf near the stream, her enormous eyes glowing fly

Little did we know of the drama that awaited her that evening. According to Bugguide,

Adult females congregate in a swarm above vegetation near water around sunset, and inflate abdominal sacs in an attempt to fool males into thinking the swollen abdomens are full of ripe eggs. The hairy legs are held alongside the abdomen in flight, supposedly to accentuate abdominal size. Males hunt small insects and bring the dead prey as “nuptial gifts” to females in exchange for a chance to mate. Males prefer to mate with the fattest and hairiest females, but the cost of being hairy is an increased chance of being caught in spider webs.

  • And then there is the strange insect that I have not yet seen, but that is making its way in our direction: the spotted lanternfly.

This introduced fly is wreaking havoc with fruit crops in Pennsylvania, just north of us, and several other states. It’s been found in one county in Maryland so far. Fortunately, it seems that we may have native fungi on hand to counter its spread – fungi that glue the fly down and prevent it from moving while it’s being consumed.

Truth in these cases is almost stranger than the fiction kids come up with.
