  • war of the ants

    I really do hate using my entymology powers for evil.

    Yet, I have been waging a war out my front door on an ant colony as they wreck havoc upon a beautiful and otherwise-thriving plum tree I’ve been trying to grow in my front yard.

    Let’s back up.

    We’ve been in our house for twenty years, and one would assume that roughly nineteen years since completing the landscaping around that new-build home we should have had time to grow a maginificent tree of some sort in the front yard.

    Most of our neighbours have trees that tower as tall as or much taller than their roof lines, granting shade and a sense of maturity to the property.

    My tree is only about two meters tall, spindly and could use another decade before I consider it a success. Why? Because it is the third tree I’ve attempted to grow in that spot. The previous two perished because of, frankly and humbly, my presumptions about my own ability to thwart the climate in which I live—and too, that Home Depot is an asshoel for selling trees to people who don’t check closely enough these things in their local nurseries that are not rated for our climate zone.

    On about six year cycles I’ve had to replant, tend, try to rescue, and eventually remove the two previous attempts at a front yard tree. And most recently, in 2020 (I remember this because it was in the peak of the pandemic’s first summer) I found a plum tree in a pot, ready for transplant, similar if not identical to the one thriving in my neighbours backyard, rated for our climate zone, and I bought it and planted it in the hole from which I’d just dug the remains of the last stump.

    Fast forward to twenty-twenty five and past four bitter winters and a couple years of light but successful plum harvests from this young tree… and to me noticing that a lot of the leaves were curling up this year and—oh shit—the ants, I suspect a species likely lasius neoniger, had infested it and had built some kind of critter farm filled with hungry little insects and webby, silky, munching aphids turning entire branches into a tree apocalypse affecting about a third of the host organism. They were killing my third tree. 

    Here we go again.

    Or…

    My last week has been spent trying to rout the invasion.

    Diatomacious earth powdered upon the ground.

    Insecticides on the leaves to curb the livestock explosion.

    Bait traps seeded around the colony in hopes of poisoning the queen.

    And, most rudimentary, spirals of sticky tape twisted around the trunk face out to capture hundreds of drone workers and glue them to their doom. 

    I studied entomology in university. I often tell people it was an unofficial minor in my science degree—unofficial because I never took the time to declare it—and I could have, should have gone on to do something with that because I love insects, particularly the eusocial ones like ants who I used to rave to anyone who would listen about the fascinating properties of ants who did agriculture. 

    I mean, I just don’t want it in my tree, in my front yard, wrecking my stuff. A bit nimby of me, sure, but I’ve got property values to think of, right? And, I mean, what a waste.

    So I sit here writing this, drinking my coffee, and thinking with the backburner thoughts of a guy preoccupied by a problem what my next move in the battle is going to be.

    Those ants outnumber me for sure, but I won’t let them outsmart me.

  • country fly, city fly

    Atop a mountain this past summer, backcountry camping for three nights an eight hour hike from civilization, I spent an hour each day keeping up my writing by scribbling narratives of our daily advenutres into my smartphone. This is one of my entries.

    day two

    Anyone in search of an example of modern evolutionary pressure look no further than the common fly. 

    Back in the city, like up high in the mountains, flies are ubiquitous.

    But unlike the mountains, the cities are filled streets, buildings, parks and coffee shops full of people.

    City flies need to be smart and fast.  Any fly that is not keenly aware of its surroundings and has not the instinctual inclination to leap into the air and off into the safety of flight is doomed to be swatted by any of a million people. Flies are not be dullards, and any fly born without the inbuilt drive to flee is unlikely to survive long enough to pass on its disadvantageous genome to a future generation.

    We will have spent nearly three days up high in the backcountry camping in the mountains where a million variety of insects thrive. In fact even high up above the tree line where even in mid-August patches of snow remain in the share of large rocks, there are so many flies that an adventure-seeker is bound to spend as much time swatting away bugs as admiring the views. And it struck me as curious—though probably less so for the fly which I smacked dead upon my bare forearm—that there must be significantly less pressure, evolutionarily speaking of course, for mountaintop flies to carry a genome that knows better than to get smacked by a human—which a fly may rarely, if ever, see in its short life on the side of a mountain—than for one of its city cousins who encounter humans as a matter of course and have no such luxury as to leisurely investigate a bare forearm on a Friday afternoon.

    Nearly every fly I encountered up on that mountain was indifferent to the risk of sudden death carried by my swiftly moving hand. Nearly every fly sat patiently and still as I reached over and snuffed it away.

    Smacking a city fly requires speed and agility on the part of a human, but one feels superhuman atop a mountain as the dull flies understand too little what awaits the looming shape and shadow of a hand moving towards them.

    Evolution at work.

  • of a hundred little bugs.

    Did I mention that I have a biology degree? It factors into this post, so it’s worth mentioning now. Bachelor of Science with a specialization in molecular genetics and minor in entomology, convocation 1999.

    I can’t say that I’ve used it much in my career, though having it has opened numerous doors.

    And occasionally it rears up as a useful bit of dormant knowledge in my head such as when I need to help my daughter study for a science exam, or I decide to open up my sketchbook and draw an insect.

    A couple weeks ago we were roaming around New York City and I was busily drawing urban sketches of the parks and the buildings and the people. We visited all sorts of sights worth seeing for any nerdy, arty sort of guy, including not only museums but also the 5th Avenue branch of the New York Public Library.

    They have a gift shop.

    And I bought a gift. For myself. A gift that was both arty and nerdy.

    I bought a leatherbound sketchbook made with lush Italian paper with an embossed logo from the library on the cover. It looks and feels like I pulled it out of the golden era of philosopher scientists, as if Charles Darwin himself might have lugged it around in his satchel to record his evolutionary observations.

    But what to do with it?

    phylum arthropoda

    As a photographer I have collected hundreds of backyard bug photos over the years. This has come useful in the last few days as the weather turned bitterly cold and the only insects to be found are the occasional housefly who doesn't know better than to knock himself against the icy window pane. Bugs are beautiful subjects and present an amazing opportunity for artists of watercolour. Some will tell you that flowers are the way to go, but the diversity of the insect world is equally as vast and colourful, and leaps beyond blossoms in complexity and interesting reference material. Recreating intricate body designs, dazzling hues and sheens, detailed hairs and eyes, or the feathery hint of translucent wings is a challenge that can be rewarding for any who attempt to paint a bug. From butterflies to beetles, dragonflies, bees, and ladybugs, even a swarm of ants can make an interesting subject.

    The obvious solution (that took me a mere two weeks to spark upon with a golden eureka moment) was something dutifully scientific.

    This afternoon, having paged through ten years of photos and plucked fifty or so macro pics of various kinds of local arthropods, I painted the first of many pages in my new notebook: a ladybug sitting upon the bark of a tree in my backyard.

    I added the name in both English and Latin as a finishing touch.

    And I love the result. Paintings of nature. Of insects. Maybe plants. Possibly even some flowers here and there. Ultimately a kind of quasi-scientific collection of art linking me back to that otherwise unused university degree. Darwin might have been proud.

  • Book: Handbook of the Canadian Rockies

    I don’t buy many paper books these days, so I caught even myself off guard when I dropped fifty bucks on this doorstop-grade loaf while on vacation over the summer, and in a souvenir store no less.

    We had spent the day in the wilderness and flipping through the pages it caught the dangling threads of my vacationing soul and pried open my wallet.

    I had woken that same morning and gone for an eight kilometer trail run up the side of a small mountain to an overlook of the town where we were staying. I’d met a friend (who had moved out to there a few years back for career reasons) and she’d led me on a 7am (and two degrees Celsius in July!) run along a quiet road and up towards the trailhead of a short day hike path that was still quiet of all human life save us. We ascended a few hundred meters of elevation into the early morning crisp air and stood on a smooth boulder with a vista view spanning what seemed fifty kilometers in multiple directions, and I couldn’t help but feel a pang of envy that she could go up there any time she wanted and I was due to drive back to the city the next day.

    Flipping through the display copy of Handbook of the Canadian Rockies by Ben Gadd that evening evoked some overlapping emotions I’d been feeling from that whole week-long excursion into the National Parks, but in particular tugged at my heart in the same sort of way that standing atop a small mountain did at the dawn of that day.

    A few minutes later I was standing at a cash register, tapping my debit card on the kiosk and watching my own copy being handed back to me with a crisp little receipt bookmark protruding from the edge.

    When I was a lot younger I was fascinated by the kinds of books that were stuffed with bounties of information, the kind of books like encyclopedias or almanacs that could surprise you with any visit. Those kinds of books you pry open to a random page and are greeted with a sub-sub-heading of some curious topic and you just read.

    This is that kind of book.

    I opened the book three times at random as I started to write this paragraph and on those three visits I was greeted with a page filled with information about local lichen species, then a page detailing the dietary habits of the mule deer, and finally a two-page spread timeline of the major geological events of the area dating back a few billions of years.

    If that kind of thing isn’t your style, you’re probably also not the kind of person to feel pangs of wonder at the beauty of a particular rock formation or pause in the middle of a long hike to contemplate a small copse carpeted by lush green moss.

    A month later I’ve consistently kept this book on my nightstand and made something of a habit of opening the book at random (if not every day) a few times per week and reading a few pages here or there about the history, flora, fauna, and geology of my nearby mountain escape…

    …and then pining to be back there.

    If that isn’t an endorsement for a book, I don’t know what is.

  • Hymenoptera

    I sometimes tell people that while in university I unofficially minored in bugs.

    As a biology student I had many options for my options, but my interest veered sidelong into a course of courses in the entomology department. I exited with a bachelors degree in genetics, but the extra educational suitcase I had brought along was stuffed full of souvenirs from my study of insects.

    Packed in that suitcase, I’ve always adored the word Hymenoptera.

    hai - muh - NAAP - ter - uh

    Or, the order of insects that contains wasps, bees, hornets, ants and other similar six legged critters.

    The summer of 2021 was apparently a good year around here for a particular kind of yellowjacket wasp.

    Popular opinion was that there was more than just an uptick in the aggressive insects population over the last few months. Call it a surge. A bumper year for hymenopterans. Nearly everyone had a story of being stung, dealing with a nest, or even the consequence of the crop of pandemic puppies encountering angry bugs for the first time either in their campsites or own backyards.

    A nearby neighbour must have had a nest in their yard and for a couple weeks solid the little drones took over a corner of my backyard and harassed the dog (who never did seem to figure out that they were never going to play nice with her.)

    I reluctantly put a trap on a tree and caught a few hundred, but to be honest it neither made much of a dent in the population nor made me feel good about myself.

    There is a balance to everything, and I noted this most acutely when (after dealing with weeks of wasps and yellowjackets in and near the city) we vacationed in the mountains and hiked for hours without seeing so much as a hint of those black and yellow stripes.

    Our attempts to control and manicure the local suburban ecosystem with the species of plants and critters we think we like, the ones that are pretty or simple or tasty, has a side effect of throwing into chaos the nature tug-of-war we can’t quite see, and which manifests as weeds and coyotes and mosquitos and wasps terrorizing those same spaces as we eliminate natural predators or encourage invaders to take refuge in the vacuum.

    The mountain ecosystem, by contrast, has seemingly still not tottered onto its side and the result is that we were able to hike without much fear of being stung.

    Eaten by a bear, maybe, but stung… less so.

    Yet now, twenty years after graduating from university I don’t do much with or recall many facts from my biology education but I have this vague sense that I can see the loose threads of the ecosystem imbalance, that I can talk and write about it with some confidence, and that one of the hundred dollar words I can always lean on is Hymenoptera.
