Eastern Comma Butterfly

Today I had an encounter with another overwintering butterfly -- the Eastern Comma (Polygonia comma). After several cool days, this Eastern Comma is taking advantage of today's sunny 58 degree weather and warming itself on my back deck.  Like the Mourning Cloak, this butterfly will hide from the harsh winter elements under tree bark or in various cavities.  At the first hint of spring warmth, it will emerge to bask in the sunshine and lay its first brood.  These butterflies are quite feisty and are known to fly at other butterflies and insects that invade their territory.   Host plants for their caterpillars include nettles, American elm, and hops.
