Comparison of Australian plague locust and Heteropternis obscurella adults
Australian Plague Locust - Chortoicetes terminifera
Major differences between adults of these species: Australian plague locust adults are readily confused with Heteropternis as both species have red tibia and dark markings on the tip of the hind wing. However, they can be differentiated by:
- the marking on the hind wing of Heteropternis is more of a general smudge rather than a spot
- Heteropternis has a stouter and darker coloured body
- Heteropternis do not turn to face the observer on landing unlike the plague locust
Also Heteropternis rarely form into dense swarms unlike the plague locust.
