Fruit Close-up
The fruit can be prolific on bushes, a mass of green then turning blackish purple or just brown, and very papery. Host plant for Fiery Jewel Hypochrysops ignita. The adult male and female butterflies look very similar. On top, they are basically dark brown, with a blue iridescent sheen. Underneath they have patterns like flames: yellow with scarlet bands outlined in black, white, and iridescent green. This is presumably the origin of their scientific name, derived from ignis, the Latin word for fire. There are also three or four black spots under each forewing.
