Erebus hieroglyphica

Erebus hieroglyphica

. The smallest Bornean species, hieroglyphica shows a similar strong sexual dimorphism to the next species. The male hindwing in both is reduced, rather triangular, but in hieroglyphica the margin is distinctly trilobed; see also the next species. In both sexes there is usually a pale cream to white bar at the costa postmedially on the forewing, with a small pale patch in the centre of the wing immediately posterior to the interior end of the bar. The development of these pale marks, especially the width of the bar, is very variable, better appreciated on the underside, and very occasionally they are absent (e.g. in the Bornean male illustrated).

Geographical range. Oriental tropics to Sundaland the Philippines and Sulawesi.

Habitat preference. Only four specimens have been recorded in recent surveys, all from Sabah: two females taken at light in lowland forest, at 300m near Tawau and at 170m at the Danum Valley Field Centre; a male and female taken flying by day at Mile 5 on the access road and at Bundu Tuhan at about 1200m near the Park Headquarters of G. Kinabalu. Both the Kinabalu localities are partially cleared and cultivated. Chey (1994) recorded a few specimens in softwood plantations at Brumas in the lowlands of Sabah.
