What is this??

It's a smoky horntail wasp.

Thanks!! there is another person on here with a photo of the same insect. I will try to find it and tell him.

OMG I am so glad I found this pick. I was discribbing it to a friend at work and she told me that it was called a ground hornet(I have been searhing the internet all evening trying to find a pic of this bug). They live underground and can be aggressive. I have been seeing them fly over my grass the past few days. I saw another pic to I will also try to find it. I live in Ohio by the way

Hi this is melody,I am a student of entomology. This is a horntail. Horntails are wasp like, brownish or black insects,3/4-1 5/8 (20-40mm)long, with cylindrical bodies.Unlike wasps,bees,and ants their thorax amd abdomen are broadly joined together, not seperated by a narrow waist. at the tip of the abdomen,on its upper surface there is a triangular plate, elongated into a spine in some species. In the females the abdomen also bears a long, slender ovipositor at the tip, wich is used for driling into the stem of plants or the wood of dead dying trees, where the eggs are laid. the catapillarlike tunnel in wood;after the larvae and pupal periods, the adults will then emerge through conspicuous holes. Adults feed on nectar and water.
