So this little dude shows up on the office window today and hangs out for a while to observe the human species at work. He flew off to observe other things after a short inspection period. I was wondering if he considered himself a butterfly or a moth. The following quote from the Library of Congress website might help you decide.
“One of the easiest ways to tell the difference between a butterfly and a moth is to look at the antennae. A butterfly’s antennae are club-shaped with a long shaft and a bulb at the end. A moth’s antennae are feathery or saw-edged.”
