Robber Fly (2) - Promachus vertebratus - male

Robber Fly (2) - Promachus vertebratus - Male
Somme Prairie Nature Preserve, Northbrook, Cook County, Illinois, USA
September 3, 2005
This second robber fly was flying around in the vegetation. With the claspers on the end of its abdomen, we would assume this is the male of the species just posted below.
