Amblychia angeronaria Guenée

Amblychia angeronaria Guenée, 1857, Hist. nat. Insectes, Spec. Gen. Lep. 9: 215.

Diagnosis

This and infoveata are easily confused.

[A. angeronaria] is paler, browner, often mottled with ochreous in the male, rather than grey, fasciated with brown. The fovea is present in angeronaria, absent in infoveata. The females are a more orange-brown in angeronaria. The medial fasciae are narrow, clearly defined in angeronaria, broader, more diffuse in infoveata. The forewing antemedial is somewhat more oblique to the dorsum in infoveata, and the hindwing margin is more strongly and broadly excavate between Rs and M1. The underside is paler, more ochreous in angeronaria, with the forewing postmedial dark band more or less straight rather than curved with the concavity distad as in infoveata. No reliable genitalic differences have been located.

Taxonomic Notes

Moore (Andamans) is probably distinct, having the diffuse medial of the next species and a less produced, more regularly excavate hindwing margin.

Geographical Range

N.E. Himalaya to Taiwan, Borneo and Sumatra.

Habitat Preference

Most records are from the forests of the lowlands, during the Mulu survey with some preference for alluvial forest and kerangas.

Biology

The larva in Taiwan is illustrated by Sugi (1987) as discussed in the introduction. It is ochreous, mostly suffused cinnamon grey-brown except for a few, large, irregular, diffuse patches of ground colour on the flanks. The host plant was in the family Lauraceae.
