  • Single-housing: from 20 x 20 x 30 cm
  • Group-housing: from 30 x 30 x 30 cm for 3 adult males
  • 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.

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

Relative humidity:
Days ~ 60 – 80 %, nights a little higher

Set-up:

  • Substrate: Soil, moss and dry leaves (animals often stay on the ground)
  • Branches (also horizontal/bent) and bark pieces
  • Living or artificial plants (Beware of pesticides!)
  • Clean with vinegar or biodegradable glass cleaner (afterwards rinse with clear water)

Feeding Recommendation

L1/L2 Big fruit flies (Drosophila hydei) or firebrats

More

With a little luck you can experience their impressive threat behavior. At rest, however, they are well camouflaged between dry branches and leaves.

Large prey is easily captured. They also like lurking near the ground.

The males are a bit shy and can fall to the ground in case of danger (and pretend to be dead). They then remain motionless for several minutes on their backs.

Females have large backwards showing tips / extensions at their pronotum (in contrast to D. lobata).
