*From (

August 16, 2020: Condylostylus patibulatus are really small. Really small. And fast. And skittish. notes that they are among the more common flies in the Northeast and one of the first to be described in scientific literature. They are also common in our yard as tiny, brightly zooming specks. Photographs of them are inevitably blurry and frequently do not show the insect, because he or she has flown off before the shutter closed.
