A beautiful tiger moth attracted to one of the lights at our Nantucket moth blitz last summer. I was lucky enough to get a shot with the gorgeous peach and red underwing exposed, too. It's difficult to tell species apart in this genus so I'm just calling this Apantesis sp. for now.
Purple Mountain Swallowtail Butterfly. Butterfly fact: There are many reasons why butterflies are so colorful. Their color helps them to blend in with flowers when feeding. It helps them absorb heat. It also helps them attract a mate.
