  • Single-housing: from 15 x 15 x 20 cm
  • Group-housing: from 20 x 20 x 30 cm for ~ 10 L5 nymphs
  • Small nymphs can be reared in smaller enclosures (for moulting they need twice their body length free space downwards)

Two ventilation areas (gaze at top + front) adviced to prevent waterglogging.

Days 25 – 30 °C, nights room temperature (below 18°C no problem)

Relative humidity:
Days ~ 50 – 60 %, spray every second day

Set-up:

  • Substrate: Soil, sand, kitchen paper, gravel, coco humus etc. (animals sometimes stay on the ground)
  • Branches (also horizontal/bent) with ~ 0,5 – 1 cm diameter
  • Living or artificial plants (Beware of pesticides!)
  • Clean with vinegar or biodegradable glass cleaner (afterwards rinse with clear water)

More

When resting or feeling disturbed Popa spurca (the small Twig mantis) often hold their fang arms elongated in front of them and press their body to the ground/branches. So they rely completely on their camouflage (as twig) and hardly do not even move when touched. This behaviour makes them seem like stubborn.

Another special aspect of this species are the reduced wings of adult females (looks like saddles on their backs).

Subspecies:

  • Popa spurca crassa is distributet along the east coast of Africa
  • Popa spurca spurca is distributet widespread throughout all Africa south of the Sahara, except in the east
