Hairy Cicada (Tettigarcta crinita)

A dark brown cicada about 50 mm long. Had prominent close set eyes and a prominent pronotum. Central and lateral patches of pale orange-cream were seen running down the pronotum. Basal part of the wings also showed pale patches. Besides these features, the pronotum appeared to be "hairy" hence the common name.
This species is seen in wet sclerophyll forest and subalpine snow gum woodland.
They belong to the primitive cicada family of Tettigarctidae and Tettigarcta is the only genus. At a glance, Hairy Cicadas can be distinguished from other cicadas by their close set eyes and prominent pronotum. It is reported that this species is not capable of producing audible sounds. Both sexes vibrate their tymbals. The sound is transmitted through the substrate and picked up by special sensory organs in all legs, called empodia. This adaptation is absent in the Cicadidae. This cicada is active in colder months.
