Found this in my backyard, but have never seen it before.
Though it resembles a wasp, this is actually a Clearwing Moth in the family Sesiidae, and many members of the family are effective mimics of wasps, a physical attribute that acts as protective mimicry. The defenseless Clearwing will be avoided by many predators who have previously been stung by wasps. Many Clearwings look similar, and we will attempt to identify your species later today as we now have some house keeping to which to attend. You can see many examples of Clearwing Moths on BugGuide. Though we at first claimed we would attempt a more thorough identification later, we decided to give it a quick try, and we believe this is a Lesser Peachtree Borer, Synanthedon pictipes, based on images posted to BugGuide where it states: “Larvae tunnel under the bark and in the twigs and branches of cultivated and wild peaches, plums and cherries (Prunus), Amelanchier, apples (Malus spp.) and pears (Pyrus) (all Rosaceae).”
