Comparison of Australian plague locust and Peakesia nymphs

​Comparison of Australian plague locust and Peakesia nymphs

Australian Plague Locust - Chortoicetes terminifera

Graphic: a 5th instar Australian plague locust nymph - note 'X' mark on top of thorax. 


Peakesia hospita and other Peakesia species

Graphic: Side view of a 2nd instar Peaksia nymph - this species lacks a distinct 'X' mark on thorax and has a stockier body with short antennae. 



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

  • thorax of Peakesia lacks the 'X' mark as seen in plague locust and has a general 'salt and pepper' mottled body of no particular strong colour
  • anntennae of Peakesia are much shorter than those of the plague locust and are darker than the body
  • Peakesia has a stockier body

Species of Peakesia do not form into dense bands as seen in the plague locust.
