The Mulberry Wing
From the looks of this thing, it seems certain to be a Bog Holomelina (Holomelina lamae), of the Arctidae family (tiger moths). According to my copy of Covell, it's found only in bogs. I'm not sure where the bog is at Muttontown Preserve. A nearby wet area is fenced off, so I've never had a good look at it. Perhaps this thing lives in other wetlands, like the Bog Lithacodia which I regularly find in sedge marshes. The date of this picture is August 18.
