What kind of Insect? #720730

On Tuesday, this insect flew into my truck in Rocky Point, Pender County. Some kind of prehistoric dinosaur bee. One of the guys on my crew said it looked like a cross between a yellow jacket and a dragon fly. I took a couple pictures. Can you tell us what it is. We have never seen it before. And we are outdoors workers.

Thank you for your question. Identifying insects and spiders based solely on a photo can be very difficult, because you often can't make out distinguishing characteristics necessary to make a positive identification. However, in your case, I can provide a tentative identification. The insect in your photo is one of the robber flies in the family Asilidae. It looks like a red-footed cannibalfly, scientific name Promachus rufipes. It is also known by another common name: bee panther.
This fly is a powerful predator. It is capable of capturing insects much larger than itself, e.g., grasshoppers, in mid-air, however it more commonly feeds on wasps, bees and other flies. Its bite injects enzymes that begin liquefying the internal organs of its prey, making it easier to ingest.
Males have a black rounded tip at the end of the abdomen. Females have a black pointed ovipositor used for depositing eggs. People often mistake this for a stinger. All flies lack stingers, but as mentioned above this species can bite.
Here's a link where you can find more information on this species:
