Geschlechter, Stadien und Stolperfallen

Geschlechter unterscheiden

♀ Weibchen

Adulte

Both sexes are wingless. The male has a clearly enlarged, upturned “scoop” at the front of the pronotum; the female’s is smaller and flatter. Underneath: the female has one large terminal plate, the male a tiny extra segment.

Nymphen

Only in the oldest nymphs, by the plates under the abdomen – the differences are subtle. The scoop develops only in adults.

Entwicklungsstadien

About 12–13 moults (sources differ), 3–5 years to adulthood. Nymphs are wingless miniatures of the adults without the scoop. In the wild the young stay with the mother in the burrow for several months.

Häufige Probleme

  • Fatal moulting deformities when loose substrate collapses – give nymphs shallow, firm substrate.
  • Unaged or aromatic eucalyptus leaves can be toxic – use only dry, aged leaves.
  • Forcing growth with heat kills nymphs or gives stunted adults; too cold – nymphs stall.
  • Breeds very slowly – usually one litter a year.
