This "critter" metamorphoses into a beautiful moth that could easily be mistaken for a butterfly.
I know the old rule-of-thumb: if it flies in the daytime it is a butterfly, if it flies at night it is a moth.
My wife put it back in the grass so that it could develop in a beautiful moth. I am going to keep my eye out for a pretty yellow and brown moth. Have a great day and enjoy nature which is all around us. Lew
