Biology

This may be the Javan species referred to Nudaria discipuncta by Piepers & Snellen (1904) who described the pupation of the mature larva within a circular palisade of long, stiff hairs. The brown-spotted, green, rather pointed pupa with an angular head is formed in the centre of this. The larva was found on a variety of plants but had never been noted to feed on them. The biology of the related N. ranruna Matsumura (Taiwan) was described by Nishihara (1992a). The larva has tufts of long (longer than the body width) setae on small, well separated verrucae. It feeds on the leaf tissue of Symplocos (Symplocaceae), Eurya and Cleyera (Theaceae), plant families favoured also by the prismostictine Bombycidae (Holloway, 1987).
