Clam Lerp Insects - Genus Hyalinaspis

Family Psyllidae

This page contains pictures and information about Clam Lerp Insects in family Psyllidae that we found in the Brisbane area, Queensland, Australia.
All species in genus Hyalinaspis construct typical clam-shell shape lerps and their host plants are Eucalyptus. They construct a simple laminate lerp in bivalves shape. Lerps may look similar in different species though it varies in shape and smoothness.

Clam Lerp Insects are sap suckers and often aggregate in colonies. They insert their stylets, or mouthparts, into the plant and begin feeding and constructing a lerp, the protection cover. Lerps are formed from the sugar and wax excreted by the insects. Those materials harden on contact with air to form the protection. Lerps vary in size and in bivalves shape.
