What in the World!!! Please Help!
I found your site about two months ago after being pinched by a beetle. Great photos, and descriptions=hours of fun. Anyway, these guys were flying around having a good time scarring my niece. I haven’t seen any like this before (we live in Central Illinois). I looked through your pages on bees, wasps and dragonflies, but couldn’t find a match. Any help would be much appreciated (and also end a family discussion on the bugs identity)! Thank you, keep up the great work and have a great day!!!!
Your mating insects are Robber Flies in the family Asilidae, possibly Giant Robber Flies in the genus Promachus.
