Eucyclodes gavissima


Diagnosis.
The pattern of white zig-zag fasciae and, more distally, spots on bright green, with blackish suffusion at the costa round the forewing postmedial is distinctive.

Taxonomic notes. The Chinese ssp. aphrodite is much larger with a broader, wine-glass shaped uncus, and broad blunt process to the apex of the valve costa. Sundanian material has the valve more curved, and apically produced, and the dorsal saccular margin is more strongly sinuous.

Geographical range. Indian Subregion; W. China, Taiwan (ssp. aphrodite = formosana); Sumatra, Borneo.

Habitat preference. The species is rare. Two specimens were taken at 300m in the mixed dipterocarp forest of Ulu Temburong, Brunei.

Biology. Bell (MS) reared the species in S. India. It is of a shape typical of the genus, mottled light brown, brown, white and tinged irregularly rufous. The pupa is bone colour, suffused pink and speckled with black. The tips of the veins of the wing cases are whitish. There is a darker dorsal line on the abdomen.

The larva sits in an S-shape, covers itself with particles and walks in a halting, trembling manner. Pupation is in a silken cocoon typical of the genus.

The larva fed on the flowers of Memecylon (Melastomataceae).
