The razor grinder was first described in 1838 by Félix Édouard Guérin-Méneville as Cicada eydouxii before being moved to the new genus Henicopsaltria in 1866. It is the type species.[2] Its common name refers to its harsh call, which has been likened to the noise of a metal grinder.[2]
Description
The razor grinder is a large cicada with a forewing measuring 50-55 mm.[1] Males and females are similar in color and markings. The head and thorax is red-brown with black markings. The wings are transparent with some brown discoloration.[2]

Razor grinders can also emit a distress call – a fragmented irregular noise – upon being seized by a predator.[5]
Behaviour
Male razor grinders sing in large groups on the main trunks of tall eucalypts, especially spotted gum (Corymbia maculata).[1][3]
Adult razor grinders are wary and flig
