These Caterpillars eat ant eggs, and probably the larvae also. They live in the arboreal nests of the ant species :
The caterpillars are off-white with a brown head and pale brown organ on the penultimate abdominal segment, and are covered in sparse short white hairs. When disturbed, the caterpillars tuck their head under the body, so that it cannot be seen.
The caterpillars grow to a length of about 2 cms. They pupate within the ant nest. The pupae are buff coloured, and have a length of about 1.7 cms.
On top, the female adult butterflies of this species are off-white with wide dark brown margins. On top, the male adult butterflies of this species are blue with wide dark brown margins. The hindwings of both sexes each have a little tail. The butterflies have a wing span of about 3 cms.
Underneath, the butterflies are cream with brown spots around the margins.
The eggs are laid in small groups on the sides of nests of the host ant species. When the caterpillars first hatch, the ants carry them into the nest. The ants feed on a exudation from the organ at the rear of the caterpillar.
