Distinguised flower fly

August 07, 2017  •  Leave a Comment


When I finally broke down and bought my 85mm Nikkor micro lens—refurbished, of course... I couldn't afford a new one—I had a minor case of buyer's remorse, which, for me, is typical with any purchase over about ten bucks. But the ennui didn't last, for no sooner had I started using the lens and focusing in on the small details of the smaller world than I realized I'd made a fabulous choice in documentary equipment. Months later, I'm still focused on the macro, and it's letting me learn new things about macro natural history: the identity of Flower Flies, in particular. I've long been a fan of these hovering tiny gems, many of which resemble bees, and I've discovered numerous books and online resources to help me uncover the Syrphid Who's Who. This one, thanks to the online Field Guide to the Flower Flies of Ontario—thank you Canada for picking up the natural history slack that the U.S. seems to be leaving in its wake—appears to belong to the genus Toxomerus, and the abdominal markings are so distinctive that I'm reasonably sure it's Toxomerus geminatus. Even more exciting, for the budding Syrphid taxonomist, is that I can actually sex the fly: the pointed shape of the abdomen marks this bug as a female.
