Lerp (biology)

Summary

In biology, a lerp is a structure of crystallized honeydew produced by larvae of psyllid bugs as a protective cover. These animals are commonly referred to as lerp insects, of which there are over 300 species in Australia.[1]

Lerps are energy rich, consisting mostly of starch, with some proteins and fats.[1] They are eaten by flying foxes, possums and birds such as pardalotes and honeyeaters.[1]

The word is derived from the Wemba Wemba word lerep.[2] Lerps are traditionally eaten by Indigenous people, and can be stored as dry balls for future use.[3]
