This is a female Peachtree Borer Moth. It looks like a wasp but you can tell it is not because it does not have a narrow wasp waist. This sinister-looking insect is bad news for peach and plum trees because it lays eggs on the trees. The eggs turn into little grubs that tunnel into the trees. When the damage is severe, the tree will die. If you have peach or plum trees, this is one insect you do not want to see.
