It is known from Tasmania. The larvae feed on Nothofagus cunninghami. They probably mine the leaves of their host plant.A moth is an insect closely related to the butterfly, both being of the order Lepidoptera. Moths form the majority of this order; there are thought to be 150,000 to 250,000 different species of moth (about ten times the number of species of butterfly), with thousands of species yet to be described.
