This species occurs in lowland rainforest habitats at elevations

butterflies are usually seen in two's and three's. Males often sit on
the foliage of bushes, and visit damp sand, particularly if covered in
decomposing leaf litter. I have also found them feeding at bird

or saplings, with their wings fully outspread, displaying the intense
reflective powder-blue scales which cover the basal area of the
forewings and the distal area of the hindwings.
