Ophiusa disjungens, the guava moth,[1] is a moth of the family Erebidae. The species was first described by Francis Walker in 1858. It is found in south-east Asia and the south Pacific, including Thailand, Japan, Tonga and New South Wales and Queensland. The adult is a fruit piercer.[2]
Similar to Ophiusa discriminans, differs in head and thorax being yellowish grey. Abdomen lack black patch. Forewings yellowish grey without black specks. A maculate line runs beyond the postmedial line. A grey and dark patch beyond the sub-apical spots, and hardly a trace of the patch at anal angle. A dentate sub-marginal line with the area beyond it reddish. Hindwing orange with the black reduced to a submarginal medial patch.[3]
Larva pale brownish, with numerous waved longitudinal black lines, between which are black specks series. There are some red between each pair of legs, and a black patch between each pair of prolegs. Small pared dorsal prominences found on 11th somites. The larvae feed on various Myrtaceae species, including Eucalyptus, Syncarpia glomulifera and Psidium guajava.[4]
