First time I have seen this fly at Chassahowitzka WMA, at first I thought it was a Robber Fly. So with a little bit of research, I found this to be a Hunchback Bee Fly.

I think this Bee fly is a little big for that juvenile Green Lynx spider, got to give it credit for its encouragement.

So from what I read… These flies gather towards yellow colored flowers. The flower above is a Leavenworth’s Tickseed..
Flies like this Hunchback Bee Fly are great pollinators and rarely get the credit they deserve. So here’s to all those Hunchback Bee Flies.. “You are appreciated!”
