Robber Fly (1) - Promachus vertebratus - Female
Somme Prairie Nature Preserve, Northbrook, Cook County, Illinois, USA

This green-eyed beauty seemed to be laying eggs on Pycnanthemum virginianum so we're thinking it's a female.

Promachus
Indeed, you have the female and the other shots are the male of Promachus vertebratus I presume. We have not found this species in Arkansas. Close to the eastern Promachus rufipes and our Promachus hinei.

Fine egg-laying shot.
