This female (on top)
Efferia aestuans (ID corrected 8/9/13)) is dining on a male (pinned below). I don't know if he got lucky before his demise, but I doubt it. Happy Fly Day Friday, for some flies, at least.Note: I believe this sort of intra-specific predation is pretty common in robber flies. I believe it is usually the females that kill the males because they (F) tend to be larger. Technical note, on this shot, I elevated one of the flash heads on my twin flash to give a more "key" and "fill" character to the lighting--taking a cue from
Dalantech. I like the results--the stronger lighting from above gives a bit more of a naturalistic look, and the background gets lit a little more uniformly.
