Euschema transducta Walker,
1861, J. Linn. Soc. Lond. (Zool), 6: 94.
Euschema aurilimbata Moore,
1878, Proc. zool. Soc. Lond.. 1878: 846
Hazis doubledayi Snellen, 1884, Tijdschr. Ent. 27: 97.
Dysphania auriplaga Warren,
1895, Novit zool. 2: 85.
Dysphania albescens Prout,
Diagnosis. This and the next species are very similar in wing markings, but D.
glaucescens has the hindwing discal spot smaller, longer transversely. The
hindwing postmedial is more arcuate in each space, and the yellow at the tornal
angle extends well interior to the postmedial (stopping at it in transducta).
Taxonomic note. D. cancellata Bastelberger, described from Borneo, appears to be
based on an aberrant specimen of transducta or the next species.
Geographical range. Burma, Peninsular Malaysia, Sumatra, Borneo.
Habitat preference. Recent records have been from lowland alluvial forest
near G. Mulu, specimens being taken flying by day and at light at night. Barlow
(1982) notes it also from hill-top clearings.
Biology. The larva and pupa are illustrated by Barlow (1982). The former is
greenish yellow with numerous black dots, particularly in an irregular lateral
row. The black dots are often highlighted by electric pale blue. The pupa is
similar but duller, less spotted.
The host-plant is Carallia. Oviposition is singly at dusk on the
undersides of leaves low on the plant (Barlow, 1982).
