Coleophoridae

Overview

The adults rest with antennae porrect. The larvae of the endemic Corythangela from eastern N.S.W. feed on Casuarina in an elongate case of pieces of the branchlets. Other endemic species are referred to Coleophora , and little is known about their early stages. An unnamed Coleophora with grey wings and veins outlined with ochreous has been reared from larvae feeding on Rutidosis . C . serinipennella makes galls in the stems of Chenopodiaceae in inland N.S.W. The bronzy green C . alcyonipennella from Europe is established in south-eastern Australia, Tas. and New Zealand, where the larva feeds on the flowers of white clover, greatly reducing seed production.
