This spectacular butterfly from the rain forests of Central America is one of the cracker butterfiles (error - should be butterflies), so called because the males make a crackling sound with their wings when they fly. Phil DeVries, author of "The Butterflies of Costa Rica', called this species "Starry Night" after the famous Van Gogh painting.
