Robber fly

Ignorance, manifested enough times, is anything but bliss for me. Truly, it's a goad, and when it's coupled with my native curiosity about the natural world, it's a powerful incentive to learn something new. So it would seem to be with a group of flies known as the Asilidae, the robber or assassin flies, in common parlance. I know virtually nothing about them, save that they're harmless, to us, but murder on other insects, which they intercept and overpower, then pierce with a vicious mouthpart apparatus that injects the prey with fast-acting neurotoxins and enzymes that paralyze the victim and liquify its innards, which the asilid then sucks dry. Ghastly behavior, to be sure, but done by a critter that is, to my eyes, quite handsome. Asilids come in a wide variety of forms, and many of them resemble their prey, thus making it relatively easy to lie deceptively in wait for a hapless meal. As my photo collection of this group of flies grows, I'm having increasing trouble remaining on the asilid ignorance fence. I'd best start learning tthese remarkable flies. Therein lies real bliss... well, or something close.
