Tryella noctua

Tryella noctua is a species of cicada, also known as the chocolate bullet, in the true cicada family, Cicadettinae subfamily and Lamotialnini tribe. The species is endemic to Australia. It was described in 1913 by English entomologist William [Lucas Distant].

Etymology

The specific epithet noctua comes from the Latin for a small owl.

Description

The length of the forewing is 19–26 mm.

Distribution and habitat

The species occurs in arid areas, from central Western Australia eastwards to the south-western Northern Territory, and adjacent north-western South Australia, to Coober Pedy. The associated habitat is mulga shrubland.

Behaviour

The cicadas are xylem feeders. Adult males may be heard from December to March, clinging to the stems of mulga and similar shrubs, emitting strident hissing calls during the day and at dusk.
