This is the largest of the Bornean species with crimson fasciae edged with black and a marginal band of slightly paler red with a zig-zag inner margin. The discal spot is black and single in both sexes, round in the female, more elliptical in the male.

Geographical Range

N.E. Himalaya, Thailand, Sundaland.

Habitat Preference

The species is frequent in lowland forest, extending more weakly into lower montane forest up to 1000m.

Taxonomic notes

Leong (2010g) illustrated the cocoon and emergent adult male of Cyana perornata. He also illustrated a larva that, from its size, was deduced to be that of perornata. It had a general velvety black appearance, with tufts of secondary setae arising from rows of reddish verrucae. There were also pairs of cream-coloured dots along the dorsum of the subdominal section, the pair on A1 being more prominent. The larva was feeding on a film of lichen low on the trunk of a large tree.
