Family Psyllidae
- This page contains pictures and information about White Fibrous Lerp Insects that we
found in the Brisbane area, Queensland, Australia. They are also known as Redgum
Lerp Psyllid.

 - Body
length 3mm, 5th instars

- The nymphs live and feed beneath the lerp and
are protected by the lerps. The lerps are made from starch, derived from the
plant sap. The adults looking like a small treehopper, are without lerps. They
have the strong hind legs, they can jump and fly.

- Those White Fibrous Lerp Insects are common on
Eucalyptus.

Nymph under White Fibrous Lerp

They may be in different instars on the same leaf. From the reference
infromation, adults can be observed on warm sunny day in winter. We did not
see one adult yet.
