Common Leaf Case Moth - Hyalarcta huebneri
Family Psychidae
This page contains information and pictures about Common Leaf Case Moths that we found in the Brisbane area, Queensland, Australia.
- Case length 50mm
- Leaf Case Moth is also known as Leaf Bagworm. The Caterpillars live in a silken case, to which they attach leaf or twigs to cover it. The Leaf Case Moth caterpillars seem to feed on the leaves of many different plant, hence, covered their bag with different plants materials.
- The appearance of Leaf Case Moth's case can be extremely variable. However, the Leaf Case Moth bag can be distinguished from other case moth bags by they covered their bag COMPLETELY with plant materials, no silken case is exposed. Also their bag is broadest in the middle, tapering to each end.
- Leaf Case Moths are common in Brisbane eucalyptus forest. They can be found on most kind of trees, including the Eucalyptus and Acacia. The female adult is wingless and never leave her case. The male is black in colour with transparent wings and dark antenna.
