Lophothripa vitea


Diagnosis.
The wings are shades of grey and black, the forewings with the basal half usually blackish with paler patches and containing ridges of raised scales. The postmedial is a double black line, irregular in course, most strongly developed in the discal area.

Geographical range. Indo-Australian tropics to Queensland and the Solomons.

Habitat preference. The only Bornean specimens seen are from Kretam on the coast of Sabah and from lowland dipterocarp forest at Barito Ulu in the centre of Kalimantan. The host-plants suggest it may be commoner in coastal habitats, though specimens from throughout the range have also been taken at altitudes up to 1000m.

Biology. The species was reared in India by Bell (MS). The larva is typically chloephorine, cylindrical with all prolegs. The head is round, hardly bilobed, slightly more soiled green in colour than the body. The body is dull, smooth, the segments well defined, with primary setae only, The colour is a clear grass green.

Pupation is in a semiovoid cocoon, usually on the underside of leaf, truncated anteriorly where it rises to a dorsal peak that overhangs the truncation, and produced posteriorly into two narrowly separated tails of silk on the leaf surface as in Dilophothripa. In the middle of the dorsum there is usually a slight tubercle of silk. The pupa is slender, cylindrically spindle-shaped. The front margin of segment A8 is raised and beaded and there is no cremaster. There is no information on sound production in the cocoon.

The larva feeds on young leaves, resting stretched out on the undersides. The host-plants recorded were Terminalia (Combretaceae) and Lagerstroemia (Lythraceae). Other known larval host-plants (Kuroko & Lewvanich, 1993; unpublished IIE records) are: Sonneratia (Sonneratiaceae); Heritiera (Sterculiaceae).
