Pseudodiacantha macklotii
(by Bruno Kneubuehler)


General Informations

  • provenience: Java
  • first culture has been imported by a zoo in London in 1946
  • the exact origin of this old culture is not known
  • further taxonomical informations ➤ Phasmida Species Files
  • this is a pure culture, and serious breeders are requested to avoid mixing this culture with similar populations from a different provenience. When spreading this culture to other breeders, then always use the full name with provenience
  • this culture has the number CLP 34  (Online Phasma Culture List)


  • sturdy, medium-sized, long-legged
  • body length ≈ 6.5 - 7.5 cm
  • bark-like, contrasty coloration


  • slender, long-legged
  • body length ≈ 5 cm
  • coloration similar to females, but less contrasty


  • freshly hatched nymphs are mottled brown
  • on how to distinguish between male and female nymphs


  • ≈ 5 x 3 mm
  • brown
  • some females lay distinctly smaller eggs, such small eggs must be elimitated from the breeding process (see photo right)

Food Plants

  • hazelnut (Corylus avellana)
    well accepted by nymphs and adults
  • Rhododendron (different species))
    well accepted by nymphs and adults
  • bramble (Rubus spp.)
    accepted only very reluctantly

Breeding, Behaviour

  • very easy to breed
  • active mainly during the night
  • nymphs and especially adults can be very frantically when being touched
  • adults can flash their red-black wings when feeling threatened - females more often than males
  • they relase a very distinctiv yet pleasant odor when feeling threatend
  • females stick their eggs into a substratum. In nature this might be moss layers or soil, in captivity they accept sand or filter wool (which is used in fishkeeping)
  • about 5 eggs per female and week
  • incubation (Cup-Incubation-method, on medium damp vermiculite) about 5 - 6 months at 20 - 24 °C
  • it is quite common that some nymphs will hatch weeks or even months after the first nymphs - from the very same batch of eggs
  • eggs can be covered with vermiculite (about 10 mm high), which makes it easier for the nymphs to hatch without getting stuck in the eggs shell
  • eggs of this species are not prone to get mouldy
  • nymphs hatch during the night
  • a humidity of about 70 - 85 % rH seems to be good enough for nymphs and adults
  • one can spray them regularly with chlorine-free water, but allow the water to dry up before spraying again
  • small nymphs can be kept in a Faunabox (or a similar cage), which shall not be too small
  • provide a cage of about 30 x 30 x 30 (cm, L x B x H) for 2 adult couples
  • males will be adult after 4 months (at 20 - 24°C), females after 5 months

Basics of phasmids breeding

  • keep only one species per cage, overpopulation is one of the main reasons for breeding failures
  • keep nymphs seperate from the adults, mainly to protect them during the crucial moulting phases
  • choose the cage big enough. When in doubt, too big is (usually) better than too small
  • a ventilator often supports good breeding results, as it seems to increase activity and feeding
  • provide enough light, but avoid direct sunlight (overheating)
  • try to keep day time temperatures below 25°C
  • a nocturnal fall of temperature is natural (down to around 20°C)
  • do not spray too much, phasmids are no fish ! Allow the water to dry up before you spray again
  • minimize disturbances (loud music, commotions, light at or during the night, opening up cages in the morning [often a moulting phase] ect.)
