Lavinia Clearwing (Hypoleria lavinia) (link to Butterflies & Moths of North America site) or Fuzzy-spotted Ticlear in my book A Swift Guide to Butterflies of Mexico and Central America. This seems to be fairly rare or at least I’m not finding much about it online. This one appeared in my kitchen as I was preparing a ham sandwich, landing first on a bottle of relish then flying to the floor where he seems to be on his last leg, though when I I examine closely the one on the floor seems a little different – hmmm. Anyway, it’s another new butterfly for me! 🙂
