Description: The recognized mimicry of butterflies of this moth family is quite profound particularly in flight and when they are at rest with their wings spread also considering they are almost exclusively a day-flying genus.
The mimicry of the milkweed or crow butterflies is Mullerian in nature in that the butterflies are noxious tasting due to their food plant and the Chalcosiinae moths produce cyanide independent of their food source as a deterrent to predation.
(Mullerian mimicry - A form of protective mimicry in which two or more poisonous or unpalatable species closely resemble each other and are therefore avoided equally by all their natural predators.)
They can be seen mainly during the spring and after the rain season.
