Red Admiral, Vanessa atalanta, from Iowa.
Aerias' Six-spotted Eighty-eight, Callicore lyca aerias, from Panama.
I was quite surprised to learn that this tiny moth-like creature we found at the light trap in Panama was, in fact, a 'moth butterfly' (Hedylidae). Usually bushy antennae like this are a good indication of mothiness, but of course with insects there are always exceptions.
