; subclass Pterygota, order Lepidoptera)
Family of small to very large moths in which the mouth-parts are much reduced, the antennae are often bipectinate, and the medial vein is forked in the discal cell of both wings. A single female may lay many eggs. The larvae generally bore into trees, and pupation occurs in the tunnel. The larvae of Cossus cossus (goat moth) smell like a goat. The family has a widespread distribution and many species are found in Australia.
