I've not been able to find anything like this on the list of butterflies and moths known to be in my area. Do you have any idea what it might be? Even a general classification of some sort would give me an idea as to where to begin looking.

Note: while he/she is seen here on a piece of styrofoam, the creature is unharmed and simply chose the scrap of styrofoam as a resting place.

Thank you very much.
