Peakesia hospita and other Peakesia species

Graphic: side view of an adult Peakesia - body colour is variable but usually has fine 'salt and pepper' mottling and hind leg tibia are often bright purple. Graphic: top view of an adult Peakesia showing wings - note absence of dark spot on hindwing. Graphic: inner view of rear leg of an adult Peakesia showing distinctive markings and colouration.

Major differences between adults of these species: Adults of the Australian plague locust are similar in size to species of Peakesia but they can readily be differentiated by their colour and markings:

  • the hind wing of Peakesia does not have a dark spot at the tip
  • hind legs of Peakesia have strong dark bars across the femur, with bright purple to red markings
  • colour of Peakesia body is variable but usually brown to grey-brown with very fine 'salt and pepper' mottling
  • Peakesia has a stockier body with wings barely longer than the abdomen

Species of Peakesia rarely form into swarms unlike the plague locust.
