This beastie was resting on my mailbox. An inch long, maybe. No visible stinger.

Dear Anthony,
Our money is on this being a Robber Fly in the family Asilidae, and many members of the family mimic bees and wasps, but alas, we have not had any luck with a conclusive species identification.  The closest match we could find is
Cyrtopogon lutatius pictured on BugGuide, and we suspect your “beastie” is closely related.  We will attempt to get a second opinion on this.

Eric Eaton provides feedback:
This is more likely an Atomosia sp.
Not uncommon in the eastern U.S., though you don’t say where it is from.

Thanks … I’ll look it up. I’m near Atlanta, in a burb just northeast of it. Suburbs but I have a lot of trees as creeks nearby.
I’d love to buy a book (books) focused on the fauna of this area. Any recommendations?

Hi Tony,
Specifically regional guide books are not that common.  We recommend The Kaufman Field Guide to Insects of North America.  A WTB? contributor, Eric Eaton is one of the authors.
