Oct 28, 2018: Anglewing



Two common anglewings (Family Nymphalidae) found at the Park are the Eastern Comma (Polygonia comma) and Question Mark (Polygonia interrogationis).  When the wings are folded up it is easy to differentiate the two species: the Eastern Comma has a white "comma" on the hindwing, while the Question Mark, in addition to the white "comma", also has a white "dot".  When the wings are unfolded they appear similar.  The best way to tell the difference is to look at the 3 dark spots on the forewing: the Question Mark (right) has a horizontal dark bar above the 3 spots, while the Eastern Comma (left) does not.
