At first glance this butterfly maybe identified as one of the comma species of butterflies or a member of the Polygonia family. Comma butterflies are identified by the white "comma shaped" mark on the underside of their wings. This butterfly has a "comma" on its wing but it is actually in the Nymphalis, or tortoiseshell, family. From its underside the Compton tortoiseshell looks similar to a grey comma except that it is larger and the punctuation mark is very thin.
