Bastilla maturata

. The general structure of the pattern is similar to that of maturescens, but there is a sharp medial boundary to the dark zone basal to the postmedial. Basal to this the wing is pale mauve that darkens slightly with progress to the base of the wing. In this basal zone there are fine antemedial and subbasal fasciae, each consisting of lines darker and paler than the surrounding ground colour.

Geographical range. N.E. Himalaya, Southern China, Japan, Thailand, Peninsular Malaysia, Sumatra, Borneo.

Habitat preference. All Bornean records are from G. Kinabalu between 1050m and 1930m (Holloway, 1976).

Biology. The larva was described by Sevastopulo (1947). The head is very dark brown, marked with creamy yellow, pink and black, particularly a large, pale yellow lateral patch. The body is pale pinkish, densely irrorated with specks that from three blackish dorsal lines, then a greyish stripe edged below by a black line, followed by an olive-green lateral stripe, a grey sublateral stripe and then another olive-green stripe. The tubercles on A8 are black and red.

Pupation was in a rather gummy silk cocoon spun in a curled leaf; the pupa has a white bloom. The larva was found when mature, so no host plant was recorded.

The adult is known as a fruit piercer in Thailand (Bänziger, 1982; Kuroko & Lewvanich, 1993).
