Eucalyptolyma maideni
Spotted Gum Lerp Psyllid
Eucalyptolyma maideni is a psyllid species in the family Aphalaridae, commonly known as the Spotted Gum Lerp Psyllid. As a member of the Sternorrhyncha suborder, it is a sap-feeding insect that produces protective carbohydrate coverings called lerps on host plants. The species is associated with eucalypt trees in Australia.
Glycaspis
Glycaspis is a genus of plant-parasitic psyllids in the family Aphalaridae. Species in this genus are strongly associated with Eucalyptus host plants. The genus includes at least two described species: Glycaspis brimblecombei (red gum lerp psyllid), a significant invasive pest of eucalyptus plantations worldwide, and Glycaspis granulata. Many Glycaspis species exhibit high host specificity, often restricted to single Eucalyptus species or closely related host groups. The genus is native to Australia, where it shows patterns of short-range endemism linked to host plant distribution.
