Corymica deducta

The ground colour is paler yellow than in other Bornean species, and both wings have a broad, dull red medial band. The wings are generally more speckled with red.

Geographical range. Nepal, N.E. Himalaya, S. China, Korea, Japan, Taiwan, Burma, Borneo, Sumatra, Bali, Sulawesi.

Habitat preference. Two specimens have been taken at altitude (1790m on G. Mulu, 1930m on G. Kinabalu) and two in the lowlands (30m in lowland forest at Labi, Brunei, and 300m on G. Santubong, Sarawak).

Biology. The larva in Japan is illustrated in Sugi (1987). It has a fawn ground colour, with a red and black head, and many black patches dorsally that grade brown laterally and divide up the ground colour in a reticulate manner. Bell (MS) described a similar larva in India.

The larva rests in a looped posture, with true legs and prolegs placed close together, generally on the edge of a leaf, and pupates on a leaf under a flattish web of grey silk on which are placed blobs of reddish exudate from the mouth (Bell).

The host-plant given by Sugi is Machilus (Lauraceae). Miyata (1983) noted Persea and Bell (MS) Alseodaphne, both also Lauraceae.
