This is very much a work-in-progress, but many North American species are shown here, most from the SE US. Mike Thomas has been instrumental in helping me try to learn this challenging group, and has provided most of the identifications. These pages would not exist without his help... and lots and lots of great days in the field chasing them. Additional help has come from Herschel Raney and Fritz Geller-Grimm, and Steve Krotzer and Dirk Stevenson have also spent lots of time with me in the field trying to find and ID this fascinating group. All comments welcome!

Note- As of June 2009, Torsten Dikow has just published a revision to the Asilidae, check this page for some details. Basically, for GA, Apocleinae has been moved back into Asilinae, Laphystiinae has been placed into Laphriinae, and several genera have been moved into a new subfamily Brachyrhopalinae.

Here are some useful links concerning asilid identification or biology:

Steve Collins has just created a new robber fly ID site based mostly on Florida but full of great information about southeastern and other robber flies, I highly recommend it!

Asilidae Fritz Geller-Grimm's excellent website for all around information and many links

Raney Robbers Herschel Raney's robber site, lots of good info, geared partly to Arkansas, plus an Eastern species key.

This site is being published in March 2020, and many of the pages have been brought over from my old site but are not yet cleaned up from transcription issue... please be patient with me!
