Reader Mike McDowell sent us some splendid photos of dipterans—robber flies. His notes and IDs are indented.
Robber flies share some of the same microhabitats as tiger beetles, with the latter often falling prey to the former. Thus, when in the field photographing tiger beetles, I often come across a variety of robber flies. They’re equally as challenging to sneak up on, so it’s a lucky day when one can leave the field with great portraiture of both types of insects. For the uninitiated, robber flies have a spike-shaped proboscis that they jab into their prey and use it to inject saliva containing a mix of neurotoxins and enzymes that paralyze and digest the insides. The devilish fly then sucks out the liquefied meal through its proboscis. Nasty!The last two are genus Laphria, but unsure of species — perhaps a reader can identify them.
Terrific pictures! Do you ever see robber flies turning their heads? I know the bumble bee mimicking Laphria will do it, but have not noticed other species doing that.
Odd but interesting-looking wee beasties. First time I encountered one of the bumblebee mimicking species feasting on a bumblebee I probably spent a good 20 minutes following it around the garden, absolutely awe-struck. Great shots!
Superbly photographed collection.
The injection of neurotoxin through a piercing proboscis could be the inspiration for a lovely horror film.
I’ve heard if you handle the robber fly and aggravate it enough for it to bite you, it really hurts. I imagine it would given that large proboscis! Think of how much horse flies hurt when they bite & they have comparatively small proboscises!
It looks to me that the one on the flower is laying eggs into it.

Amazing macros!
I love robber flies with their moustaches!!
Great photos. The time and patience required must have been enormous.
Beautifully done shots. Really sharp and also shows the flys’ personalities.
Thank you. Enjoyed notes and excellent photos.
they’ve got Bette Davis eyes!!!
Terrific shots! Some of the flies look to be standing on beach sand.
The sand in the photos is gorgeous!
