Ive joined an insect forum to ask as well, but i thought i would at least try here. Any help would be appreciated since i am a collector
Panacea procilla from Central and South America. Would be MUCH, MUCH easier if you had said where it was photographed. Even if is a butterfly hall (I guess it is since you posted in on a zoo forum) because many have homepages with species lists or get their butterflies from 1-2 suppliers and you can limit the possibilities from that.
