Robber Fly, we presume

Dear Beck Shawn and the 3 kids,
We cannot imagine that this is anything other than a Robber Fly in the family Asilidae.  This individual looks like the same species as this previous posting of a Robber Fly from Melbourne submitted in December 2012.  It is not uncommon to have seasonal sightings of species of insects as most live no more than a few weeks as adults.  Robber Flies are top of the insect food chain predators that can take other predators, including Yellowjackets and other Wasps, on the wing.  Like other flies, Robber Flies have a single pair of wings, yet having one pair less than most insects seems to have improved rather than to have inhibited their ability to fly.
  Perhaps one of our readers will be able to assist in this identification.

I took this photo a few years ago and came across it again today. I can’t figure out what these bugs are. Can you help?

While we are unable to provide you with a species, we are quite certain that this is a predatory Robber Fly in the family Asilidae.

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.
