Habitat and Range
Geographic Range
Native to E. Australia; introduced in So. CA.
Diet and Behavior
Diet: Host: Corymbia (formerly Eucalyptus ) citriodora (Lemon-scented Gum) & C. maculata (Spotted Gum)
Life History
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.

About True Bugs, Cicadas, Hoppers, Aphids and Allies: the wider group
Order-level background for Hemiptera, the group containing Cryptoneossa triangula. Species-specific details appear above.
Group overview
Hemiptera (true bugs) includes over 80,000 described species across cicadas, aphids, leafhoppers, shield bugs, and bed bugs. Aphids alone cost global agriculture an estimated $2.5 billion annually in crop losses.
Ecological role of the group
Many Hemiptera are essential food sources for birds and predatory insects. Cicadas provide massive nutrient pulses during emergence events - a single Brood X emergence can involve trillions of individuals across 15 states.
Economic and practical significance of the group
The brown marmorated stink bug (Halyomorpha halys) caused $37 million in apple crop losses in a single year in the U.S. Mid-Atlantic region. Bed bug infestations in the U.S. increased by 500% between 2001-2010, costing the hotel industry hundreds of millions annually.
