Common Eggfly, Male (Hypolimnas bolina)

Also known as, the Great Eggfly, Varied Eggfly or in New Zealand, the Blue Moon butterfly - a generally common butterfly across most tropical and sub-tropical habitat types, including wet/dry woodland, found from Madagascar to Asia and Australia.

 

Males are monomorphic. The dorsal wing surface is jet black but features three prominent spots, two on the forewing and one on the hindwing. To a human observer these appear as white spots fringed with blue-violet. They actually consist of a white centre overlain by bright ultraviolet iridescence. The ventral surface lacks any ultraviolet iridescence and consists essentially of banded white markings set against a brownish background.

 

Females are owing to the presence of both genetic polymorphism and phenotypic plasticity; polymorphism is expressed primarily on the dorsal surface. The female ventral wing surfaces are similar to those of the male.
