Earlier this month I spotted a butterfly with perfect colors for Halloween and it was perched upside down in a way that reminded me of a bat. (Take a close look at its shadow.)
It’s not really called a Halloween Butterfly—I sometimes like to make up my own names for the creatures that I see and photograph. It was a cool, but sunny day when I came upon the butterfly, which was completely stretched out, basking in the warmth of the sun’s rays. I wasn’t sure it was alive, until it flew away when I moved in a little closer after some initial shots.
The unusual wing shape made me think it was either an Eastern Comma or a Question Mark butterfly—yes, there are butterflies named after punctuation marks—but I wasn’t sure which one. After a little research on line, I’m convinced that it is probably an Eastern Comma butterfly (Polygonia comma). According to a posting on Trekohio.com, Eastern Comma butterflies have three dark spots in a row on their front wings, while Question Mark butterflies have four spots.
Why am I seeing a butterfly this late in the season? Eastern Comma butterflies overwinter as adults. A University of Wisconsin-Milwaukee Field Station posting described the process in this way, “They overwinter in cracks and crevices in rocks and trees. There, they certainly freeze, becoming butterfly-sicles, but their blood contains glycogens – antifreeze – that allow their tissues to withstand the winter’s cycles of freezing and thawing.”
In spring, the un-dead arise again.
Happy Halloween.
