The flowers of this diminutive species are irresistible photo subjects, and when I came across a drift of especially colorful specimens in Wilderness State Park last week, I naturally started in with the camera. It wasn't long before I noticed this tiny flowerfly in the family Syrphidae plunging into the pollen-laden depths of the flowers. A great many of our wildflowers depend upon insects to move pollen from plant to plant, and scores of species of flies play a major role in pollination.
The spider, which was hanging in the web, made no move to approach the ferocious predatory flies. Finally, I moved in a bit too close, the flies stirred from their trance and easily broke free of the web, flying to a nearby leaf to continue on. Even a venomous arachnid caused no worries for the six-legged beasts. Woe to any creature their size or smaller than crosses paths with one of these flies when it's hungry. Or perhaps interrupts them in flagrante delicto.
Robberflies are the Peregrine Falcons of the fly world.
