Indeed Machimus (Tolmerus) cingulatus. As far as i know robberflies don't take dead prey. Cannibalism is not uncommon among them and this could also have been her mate.
Funny, that first the backpart is dissapered..
Thank you for your information Reinoud, nice to know..
As you know I'm always thanking you for naming my flies!
You are welcome, you keep me from the Streets : ) Robberflies suck their prey dry but do not "eat" parts, maybe the other one got mutilated during mating. ??
