Coming in to the lab this morning, I found this beautiful male Laphria robber fly sitting on a window. He was still cool from the night, so he made a very cooperative photographic subject.
These large handsome flies are strikingly marked and are Batesian mimics of bumblebees. Robber flies do not rob banks, they rob life. For a great example of this, see Alex Wild’s wonderful photo of one with a honeybee.
This robber robbed me of about 30 minutes of photography time, but I think it is well worth it!
