Trabala krishna Roepke

Trabala krishna Roepke, 1951: 117.

Diagnosis

The male is bright green with a strong discal spot and submarginal spots, the latter with a marked central ‘step’ and acutely dentate distad.

The fasciae are yellowish, crenulate on both surfaces.

The fringes, particularly of the hindwing, are crenulate and darkly edged.

The uncus has two well separated and slender prongs; the aedeagus apex is only weakly produced.

For diagnosis of the female see the previous species: the submarginal spots are perhaps never pale-centred; those anterior to the hindwing ‘step’ are weaker than the rest as in the male.

Geographical range

Sundaland.

Habitat preference

The species is less common than the previous but is recorded from a similar range of lowland habitats; three weakly marked males were taken by T.P.G. Helps in mangrove in Brunei.

Biology

Host-plants givenby Roepke are Barringtonia, Melastoma, Psidium and Ziziphus. The species has been reared from Macaranga (Euphorbiaceae) in Peninsular Malaysia.

The larvae crowd on the trunk during the day, moving up to feed on the foliage at night (Tho Yow Pong, pers. comm.).
