Adults of fruit Piercing moths are fruit piercer, causing fruit rot and dropping. There are many species such as Othris fullonia Clerck, Rhytia hypermnestra Crammer, Eudocima salaminia Febricius, which may be misuderstood, because there are some difference and similarities of external morphology. Insects are captured from some areas of Chiang Mai and Lampoon, three species of the larvae are fed with three different species of host plants separately. The host plants are Tiliacora traindradra Diels, Tinospora crispa (Linnaeus), Hook F. and Thomas, Tinospora sinensis. Similarities occur in egg and pupal stage. Of seven instars in larval stage, the first two instars are most similar, but the latter instars are different in colour spot and postural behavior. The front wing of the three species are dislike in colour and patten.
