#flybuary day 4! promachus yesonicus is called シオヤアブ (shioyaabu, salt peddler "horsefly") in japanese because of the male's white tail. promachus are huge robber flies and are one of the few genera of asilids that lay frothy white egg masses. buy his salt or else.

Ahh the problem with common names
The original description of this image -'Fruit flies undergo a prelude of dances prior to mating'
It's a Tephritidae - a fruit fly. NOT Drosophila - what many refer to as a fruit fly (from family Drosophilidae aka Vinegar flies). Quite different (see image of cat)

Don't let this delicate little muppet fly fool you - larvae are voracious predators of armored scale insects! A member of the "gall" midge family, it has abandoned plant feeding for a meat-based diet (like many others).
