Pareuchaetes pseudoinsulata Rego Barros, 1956, Revta Bras. Ent ., 6: 79.

Diagnosis

The wings and thorax are uniform pale yellow, the abdomen deep yellow with a dorsal row of black spots.

Geographical range

Venezuela, Trinidad; introduced and established in Sri Lanka, Borneo, Palawan and Guam.

Habitat preference

Probably weedy habitats in agricultural areas afflicted by Chromolaena odorata.

Biology

The larva is typically arctiine with numerous moderate secondary setae on verrucae. The ground colour is blackish, with interrupted narrow white stripes dorsolaterally and ventrolaterally.

The species is probably specific to Chromolaena odorata (Compositae) and close relatives in the Eupatorium complex (Cock & Holloway, 1982).
