Episothalma robustaria

See the generic description and the account of Euxena albiguttata on (Euxena Warren).

Geographical range. Indian Subregion to Sundaland.

Habitat preference. The two specimens taken in recent surveys were from alluvial forest at the foot and in primary forest on the lower slopes (250m) of the limestone G. Api near the Melinau Gorge.

Biology. The larva was described by Bell (MS). The head is squarish, the vertices conical but not strongly bifid. The body is cylindrical, with A10 slightly conical dorsally. The skin is granular. The colour is leaf green with a dark green dorsal line. There are oblique dark lines coming from the dorsal line on each sgement anteriorly to the posterior margin at the level of the spiracle. There is dark green suffusion in the angle between these lines and dorsal line. The spiracles are sometimes surrounded by pink.

The larva adopts a stick-like resting posture, the markings resembling the leaflets of the host-plant. Pupation is within a silken cocoon spun amongst these leaflets.

The host-plants are shrubby species of Acacia (Leguminosae).
