Though it looks like a caterpillar, this is actually a Sawfly larva, and Sawflies are non-stinging relatives of bees and wasps. Based on this BugGuide image and this BugGuide image, we are confident it is Trichiosoma triangulum. According to BugGuide: “Larvae feed on leaves of alders (Alnus), ash (Fraxinus), poplars (Populus), willows (Salix), cherries (Prunus).”
