Eurybia lycisca
Saw this moth on the window in our room late in the afternoon. Not sure what species. I call it a moth instead of butterfly because it didn’t land with wings folded.
Tropical rainforest of SW Pacific coast of Costa Rica
About 1.5” wide. Update: Brian38 successfully identified this butterfly as a Blue-winged Eurybia Butterfly (Eurybia lycisca).
Welcome Bill! Beautiful shots! The easiest way to tell moths from butterflies (although there are a some exceptions) is that butterflies have thin antennae that have a little ball on each tip or club-shaped tips.
Hi Bill and welcome to Project Noah. Great first spotting! This is actually a butterfly and in the family Riodinidae (metalmark butterflies). These tend to be on the smallish size for butterflies, but extremely beautiful.
