Explanation of Names
Cryptoneossa triangula Taylor, 1990
1.8-2.6mm (1)
Native to E. Australia; introduced in So. CA. (2)
Host: Corymbia (formerly Eucalyptus) citriodora (Lemon-scented Gum) & C. maculata (Spotted Gum) (2)
Life Cycle
Nymphs create no apparent waxes and are not particularly injurious to its hosts, but are often found on the same trees as the Spotted Gum Lerp Psyllid (Eucalyptolyma maideni) which creates conspicuous lerps on the undersides of leaves. Nymphs of Cryptoneossa triangula may take shelter under these lerps, moving freely in and out of them.
First detected in California in 1995.

Spotted Gum Lerp Psyllid is often found on the same trees; while the adults are easily distinguished, care should be taken in identifying the nymphs, especially those found underneath lerp.
