  • therefore pass on this info when you distribute this species under this name!
  • 2008 - first succesful culture of this species by Thierry Heitzmann (Philippines), but he distributed them as Sosibia cf morio
  • 2009 - first successful culture in Europe by Bruno Kneubühler
  • 2009 - this species has been distributed under the preliminary name Namen Asystata sp. "Quezon National Parc"



  • this species has been collected by Thierry Heitzmann (Philippines) in 2008 in the Quezon National Park (Atimonan, Quezon Province, South-West Luzon)



  • thin phasmids, about 8,5 - 9 cm long
  • wings are well developed, but they have seen flying (so far)
  • the coloration is very variable, it ranges from almost white to dark brown with random whitish spots
  • antennae are long



  • even thinner than the females
  • about 6,5 cm long
  • wings are very well developed, and they are capable of flying swiftly and for a longer distance (at least some meter)
  • antennae are longer than the forelegs
  • coloration of the males is also very variable - though the tendency is that they are darker than the females



  • about 2 x 1,5 mm
  • dark with a whitish net-like structure
  • roundish


Food Plants

  • nymphs feed very well on Hypericum (e.g. the ones used as ground coverers in gardens)
  • they also like raspberry (Rubus sp.)


Breeding notes

  • an easy to breed and interesting species
  • incubation of the eggs on damp (not too wet) sand, with springtails to reduce mould growth
  • incubation time at room temperatures (20-23°C) about 6 weeks
  • hatching ratio was here more than 50%
  • nymphs and adults can easily be kept in a Faunabox (or a similar cage)
  • I do not spray my culture, a constantly wet paper towel on the cage floor provides enough humidity
  • nymphs as well as adults wriggle about frantically when being touched by hand. This looks like a fish that wriggels on land or as if they have an epileptic seizure
  • males will be adult after about 2 months, females after about 2,5 months
  • females start to lay eggs after about 2 weeks
  • eggs are just being droped to the ground
  • matings can be seen frequently
