General Notes

  • Redtenbacher (1906) described this species first as Phasma bispinosum
  • 2010 - imported and cultured for the first time by Bruno Kneubuehler
  • 2010 - identified by Oskar Conle as Pseudophasma bispinosum

Origin

  • P. bispinosum "Tena" has been collected by Michael Wüst (Switzerland) in Tena (Ecuador) in March 2010

_________________

Females

  • very elegant appearance
  • about 8.5 - 9.5 cm long
  • basic colour are different shades of brown with some black areas
  • black thighs (femorae)
  • light brown lower legs (tibiae)
  • forewings (tegminae) are elongated into two pronounced yellow spikes
  • black eyes
  • dark antennae which are longer than the forelegs

_________________

Males

  • appearance and colouration is the same as for the females
  • but they are thinner
  • about 7 - 8 cm long
  • antennae distincly longer than forelegs

_________________

Nymphs (L1)

  • about 1,5 cm long
  • brown with many fine, light-coloured dots - especially on the legs
  • antennae tip with a light-coloured area
  • antennae longer than forelegs
  • distinguishing sexes is easily possible by L2 by means of the presence (male) or absence (female) of a poculum

_________________

Eggs

  • about 3 x 2 mm
  • brown to grey-brown
  • light-coloured micropylar plate
  • strongly furrowed
  • not shiny

_________________

Food Plants

  • nymphs do feed well on privet (Ligustrum sp. - especially the wild growing European species), Lonicera nitida (a common ground covering plant in gardens), deadnettle (different Laminum spp. - one of the first plants to grow in spring)
  • young nymphs like fresh leaves a lot
  • adults feed well on privet (Ligustrum sp.) Lonicera nitia and Salal (Gaultheria shallon)

_________________

Behaviour

  • freshly hatched nymphs are quite active and wander about also during the day
  • older nymphs like to hide out in a dark place during the day
  • nypmhs and adults try to crawl away from danger, just to freeze again after a short distance
  • males fly well
  • females can also fly, but do so for just  a short distance
  • if adult specimens feel very much threatened, then they can spray a defensive liquid from glands just behind their head (which they do only rarely)
  • males can stay for some days together with the same female
  • females start laying eggs about 2 - 3 weeks after their final moult
  • eggs are just dropped to the ground

Breeding Notes

  • an easy to breed species
  • incubation with the HH-method (on slightly damp sand) yields a good hatching ratio
  • some moss spread over the eggs reduces mould growth and strongly facilitates successful hatching
  • incubation time at room temperatures (20 - 23°C) is about 3 -4 months
  • hatching ratio for the first generation was very high (75+ %)
  • keep the nymphs in a cage with good ventilation
  • take care that the humidity does not drop too low
  • a constantly wet paper towel on the floor of the cage helps raising humidity
  • move nymphs to a bigger cage as they grow bigger
  • nymphs and adults can be kept in a Faunabox (or similar cages)
  • I have never sprayed nymphs or adults with water
  • make shure that nymphs, which are about to undergo their adult moult, do not find places in the cage which would not offer them enough space beneath to moult successfully
  • males will be adult after about 3 months (at 20 - 23°C), females after 4 months
