Thanks to the wonderful ID skills of the folks over at bugguide.net, I can confidently say that the moth of the day (seriously, there are hundreds of them in my backyard–the only problem getting pictures of them is that they don’t alight often and they’re skittish on approach) is Melanchroia chephise (White-tipped Black – Hodges#6616):
This one is resting on the frond of a small Sabal palmetto (Cabbage palm) that still has a bit of the overnight rain (or the morning sprinklers, not sure which) on it. It’s already hot and humid, and these black-winged moths definitely prefer to rest in the shade. Only mad dogs and Englishmen…
