Do you have any idea what this guy is? I would hate for it to bite me.

Hi Tonyh,
This is a predatory Robber Fly in the genus
Diogmites, and members of the genus are commonly called Hanging Thieves.  We personally think that Hanging Thieves look much better living than dead.  Hanging Thieves are adept predators that take prey on the wing, and they often feed on large stinging insects like wasps.  Though we would not discount the possibility of being bitten by a Hanging Thief, we have never received any reports of such a bite and from all we have read, Hanging Thieves are not interested in biting humans.  Because it appears that this Hanging Thief has met with an unnatural end at human hands, we are tagging this posting as Unnecessary Carnage and we hope that should you encounter a Hanging Thief again in the future, that it be allowed to fly off to live a full life preying on other flying insects.

Thank you for the reply.  This guy managed to get into the bar at the local yacht club and a frightened member read a page of the local news paper to him.  Too bad since he is a predator of the bugs that pester us the most down on the water.  I will post the info from below to the yacht club web site in hopes of educating the membership and saving the next hanging Thief we encounter.
Thank you again for the info.
Tony Hines.
here is a link to the post on FB.  We will try to do better next time:

Dear Bugman,
I came out of the store this afternoon and noticed these 2 creatures perched on my car. At first they were lined up, but then one turned around so their tails were touching. I’ve never seen anything quite like them! They appear to be a cross between a bee and a dragonfly? I’m quite curious to find out!

Dear Sarah,
We are amused that you encountered a mating pair of Red Footed Cannibalflies, yet you composed your images to show only half of the pair.

Thought this might be a cicada, but I’ve never seen such a hairy one before or with such huge eyes.

Dear Alicia,
This magnificent, predatory Robber Fly is commonly called a Red Footed Cannibalfly, and this summer we have received more than the typical number of identification requests of Red Footed Cannibalflies from our readership.

This enormous predator buzzed down to enjoy its dinner on an elk antler in my yard – what is it?

Giant Robber Fly eats Bee

Giant Robber Fly eats Honey Bee

Dear Alicia,
This is one of the best feeding Robber Fly images we have received all summer.  This is a Giant Robber Fly in the genus
Promachus, a genus well populated in our archives this season due to all the images we have received of Red Footed Cannibalflies.  This is a different member of the genus, and we believe it is Promachus albifacies, a species with no unique common name.  You can compare your individual to this image on BugGuide.
