Major differences between adults of these species: Adults of the Australia​n plague locust are similar in shape and size to Urnisa but differences in colour and markings are obvious:

  • Urnisa body is much more mottled in colour than the plague locust
  • forewings of Urnisa also more mottled and from above have a yellowy stripe that splits where it touches the thorax
  • hind wings of Urnisa are sometimes darker at the tip but do not have a distinct spot as seen in the plague locust

Urnisa adults do not form into swarms unlike the plague locust. Hind leg tibia varies in colour from purple to red. Urnisa is only found in red sandy country.
