Stick Insect - Ctenomorpha chronus

  • Order: Phasmatodea
  • Family: Phasmatidae
  • Subfamily: Phasmatinae
  • Ctenomorpha chronus (Gray, 1833)
In the two years I've been at at this site I have never seen this species but in the last 2 months (April to June) several females have been found on the walls and windows of the house.

There are only 3 species of Phasmids in Tasmania. This one, Ctenomorpha chronus, belongs to the subfamily Phasmatinae while the other two belong to the subfamily Tropidoderinae.

This females of species can grow to 176mm, however, they can appear longer as they rest with their forelegs outstretched. They blend in well amoong Eucalyptus stems. While males are fully winged, the short tegmina and very long cerci suggest this one is a female.

  1. Great pics!
    What are the other two species of stick insect that occur in Tasmania?

  2. Thanks Nuytsia - sorry I somehow missed your comment until now.

    The other two are from a different subfamily, Tropidoderinae. They are:

    Didymuria violescens Leach
    Parasypiloidea tener (Brunner von Wattenwyl)
