A Butterfly in Winter

The other day I drove to Sunken Meadow State Park on the north shore of Long Island.  I was there to purchase a Stargazing Permit, which I do each year.  It allows a person to enter some of the state parks on Long Island after dark to do observing.  You must have a telescope or binoculars with you to be legit.  Anyhow, I passed this butterfly, which is painted metal, on the way into the office.  I have no idea why it is here, but it was bright and pretty and incongruous so I thought it would make a picture!
