Porsica punctifascia

The forewings have a ground colour darker than in benderi with the medial area surrounding the reniform suffused brownish, highlighting the kidney-shaped surround to the brown crescent. The last character is not readily apparent in the specimen illustrated.

Geographical range. N.E. Himalaya, Hong-Kong, Peninsular Malaysia, Sumatra, Borneo.

Habitat preference. It is probably a lowland species. Of the four Bornean specimens examined, three were from Samarinda in eastern Kalimantan and one from 300 m in hill dipterocarp forest, Lower Temburong, Brunei.

Biology. The species has been reared, photographed and described by M. Bascombe in Hong-Kong. The mature larva is 48 mm long, the stematopods a slightly further 20 mm. The first pair of prolegs are reduced, not used when in the resting posture. The ground colour of the body is a glossy, pale, bluish green; the stematopods are greyish with numerous small black spines. The head is speckled with deep reddish brown and the body bears several irregular longitudinal lines and bands of this colour, most fine and intense through the line of the legs. The pinacula are protuberant, also brown, bearing short brown setae. In dorsal view there is a central greenish band, bordered by narrower pale blue bands, these in turn giving way to subdorsal brownish bands which are bordered narrowly with darker brown, all these longitudinal bands being somewhat irregular. Pupation time was just under two weeks; no cocoon was made, the pupa being formed on the cage floor. The host-plant was Aporusa chinensis (Euphorbiaceae).
