Comparison of Australian plague locust and Caledia captiva nymphs
Australian Plague Locust - Chortoicetes terminifera
Caledia captiva
Major differences between nymphs of these species: Nymphs of the Australian plague locust are similar in size and shape to Caledia but differences in the antennae and markings on the thorax are obvious:
- antennae of Caledia nymphs are much shorter and lighter than those of plague locust nymphs
- early instar Caledia nymphs have a pronounced white triangle on the side of the thorax but this is lost in later instars
- late instar Caledia nymphs develop a distinct 'V' on top of thorax rather than a full 'X' as seen in plague locust nymphs
Caledia is wide ranging but more likely to be encountered in wetter coastal areas where plague locusts are rare. Caledia nymphs do not form into dense bands as seen in the plague locust.
