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.

[2] Lerps are traditionally eaten by Indigenous people, and can be stored as dry balls for future use.
