Bug of the Week - November 4, 2009

I seem to be on a bit of a Diptera kick lately (there's your first hint). For those of you new to the Bug of the Week challenge, each Wednesday I post an image of a mystery insect. Your job is to uncover its identity. Post your answer here in a comment, and if you're correct, I'll give you a shout out in next week's post. I always provide a few clues in the forum, should you need a little extra help.
Last week's winners are weirdbuglady, Mobugs41, Moni, and Mike, all of whom recognized the mystery critter as a vinegaroon or whipscorpion. These arachnids are known for their defensive behavior - they flick their tails and spray acetic acid (essentially vinegar) at their attackers.

Well, you did give good hints, but I could only come up with “a fly” until I went really searching! Cool insect!!
Bristle fly? I believe their larvae are parasitic and valued as pest control (caterpillars etc.).
I believe this is a tachinid fly of some sort. They are always hard for me to ID to species. I know they love flowers, especially when the peppermint is in bloom. I will always have several nectaring there.
I agree with MoBugs41. It is a tachinid fly.
I agree..tachinid…maybe in the genus Juriniopsis?
