General Description

Adult with two pairs of membranous wings, resembling a cicada. Young nymph wingless and secretes a smooth, white, conical covering (lerp) that resembles a shell. Body up to 8 mm long.

Biology

Sugar Lerp nymphs excrete honeydew that causes the growth of black-grey mould on leaves, but their feeding does not kill the leaf. Ants collect honeydew from the nymphs. The lerp cover provides protection from the weather, but does not prevent predation by birds and mammals.

Distribution

Central and Eastern mainland Australia and Tasmania.

Habitat

On eucalypt trees.
