I have a few photos I thought you might like. A few summers ago I was throwing pottery outside in central Kentucky and this moth couldn’t resist the tasty clay slip covering my hands as I threw. It nibbled for hours, and even though I shooed it away again and again (its tongue was ticklish as I tried to concentrate on my pottery), it wouldn’t take no for an answer! Great site; thanks for the great information.
This is a Hackberry Emperor, Asterocampa celtis. Some butterflies are know for puddling, or drinking water from muddy rain puddles. The are attracted to the moisture as well as to the rich minerals in the mud. Your photo is great.
