I'm going to rely on you folks to tell me what he is. Spotted him hopping in front of lawn mower so I stopped and ran inside to wash my hands and grab the camera. Put him on window sill for safe keeping while I finished that section, and planned to put him in a tree when I was done but when I came back, he was gone.
Unless he followed me, I don't think I mowed him over. But I've sprayed pesticides where he was hanging out, which is why I wanted to place him in a tree.
