Pyrgomorphidae

Mating pair of Atractomorpha sinensis, from here.


Belongs within: Caelifera.

The Pyrgomorphidae are a family of grasshoppers characterised by the presence of a median longitudinal sulcus (groove) extending backwards along the fastigium of the vertex of the head (Rentz 1996). They are diverse in appearance, and some are brightly coloured. The Psednurini are slender, stem-like grasshoppers endemic to Australia that can be found sitting head-upwards on upright monocotyledonous plants (Rentz 1991).
