Nygmia fumosa

Nygmia fumosa

The male forewings have a pale yellow ground with two distinct overlays: a grey shading that is broadly basal to the discal spot and in an oblique postmedial band; a more sparse but uniform speckling of black scales (See Nygmia dirtea Swinhoe comb.n). In some specimens the grey extends over the whole wing. The female forewings are a deep rusty brown, uniformly and extensively irrorated with black.

Taxonomic note. The male genitalia of this and the next species are similar, and have uncus, valve and aedeagus vesica structure consistent with placement in Nygmia.

Geographical range. Sundaland.

Habitat preference. This species is of similar ecological range and abundance to moalata (See Nygmia dirtea Swinhoe comb.n).

Biology. Yunus & Ho (1980) recorded the species (as ridleyi) as feeding on Eugenia (Myrtaceae) and Mallotus (Euphorbiaceae). There is an unpublished record of Shorea (Dipterocarpaceae) at FRIM.
