General Notes

  • provenience: Tapah Hills, Peninsular Malaysia
  • 2011: successful culture by Olivier Salord (FR)
  • 2016: fresh culture by Bruno Kneubuehler (CH)

_________________

Females

  • green with reddish to brown spots on the whole body for most of the females
  • some specimens are almost entirely green
  • size is about 8 cm, with only very flimsy variations between the different specimens
  • on the other hand, different females will show a variety of shapes. Some showing rather straight, spear-like abdomens. But others have more or less pronounced lobes along the edges of the final abdominal segments, making them look similar to Ph. jacobsoni and Ph. philippinicum
  • a pair of fore wings cover the abdomen almost completly
  • a pair of tiny vestigial, withered, elytrons, is visible under the wings
  • antennae are about 3 mm long
  • coxae (the membrane by which the legs are attached to the abdomen) are deep blue

_________________

Males

  • typically spear-like shaped
  • with fully developped wings - making it possible for them to fly easily
  • size is about 6 cm
  • antennae are about 3.5 cm long
  • coxae (the membranes by which the legs are attached to the abdomen) are deep blue

_________________

Eggs

  • about 5 x 3 m
  • compact when fresly laid
  • they get their typically hairy appearance when they remain for a few minutes in a moisty environment
  • but once they are stored in a dry environment again, they tend to stick to any material that they had previously been in contact with when wet
  • they show an amazing variety of colours, ranging from pink to dark brown

_________________

Food Plants

  • the following food plants have been accepted:
    Salal (Gaultheria shallon)
    bramble (Rubus sp.)
    oak (Quercus sp., summer green)
    evegreen oak (Quercus ilex)
    hazelnut (Corylus avellana)
    beech (Fagus sylvatica)

_________________

Behaviour

  • young males and females as well as sub-adult specimens will spray an orange-like smelling substance when being handled

Breeding Notes

  • not an easy species to breed, as first-instar nymphs and some adult, egg-bound females sometimes die without any obvious reason
  • incubation using the "on-a-net-over-wet sand" method
  • incubation time is 3.5 to 4 months at 25° C
  • high hatching ratio, close to 90%
  • broad daylight and moisture tend to stimulate hatchings
  • newly-hatched nymphs seem to enjoy daylight for their first week
  • newly-born nymphs often die, if they hatch between October and April.  To avoid that, supply them with a source of artificial lighting 12 hours/day (any type of bulb will do fine), and keep them at a constant temperature ranging between 23°C-25°C
  • by L2-L3, they can be kept at room temperature (18°C-21°C), and the light will no longer be necessary
  • they also like to drink out of small droplets
  • males grow up in about 4 months, females in about 5 months
  • the females' lifespan is about 5 - 6 months
  • females start laying eggs after about 2 - 3 weeks
  • they will lay hundreds of eggs
  • eggs are just dropped to the ground
  • males will live for 3 - 4 months, and mate easily
  • adults must be kept in a roomy enclosure - to prevent them from gnawing each other
