General notes

  • Orginally described by Bates (1865) as Lonchodes forcipatus
  • Synonyms:  Lonchodes duivenbodei (Kaup, 1871); Dixippus furcatus (Brunner v. Wattenwil, 1907),  Periphetes sangirensis (Dhorn, 1910)
  • 2008 - first successful culture of this species by Sigetake Suzuki (Hokkaido, Japan)
  • 2009 - first successful captive bred culture of this species in Europe by Frank Hennemann (D)

_________________

Origin

  • in 2008, S. Suzuki (Japan) got eggs of this species, which were collected in Bugadidi (South-Sulawesi) (F. Hennemann, pers. comm.)

_________________

Female

  • these are sturdy creatures which become very fat, once they start to lay eggs
  • up to 10 cm long
  • the basic colour is a very strong, metallic green

_________________

Male

  • up to 8 cm long
  • just after their adult moult, their thorax is coloured in a very luminous orange
  • this turns to a less luminous orange-brown within a few days

_________________

Nymphs (L1)

  • about 17 mm long
  • antennae are about the same length as the fore legs
  • tips of the antennae are brown
  • legs are banded and brown in colour
  • body colour is greenish-brown
  • nymphs hatch before daybreak
  • the nymphs of P. forcipatus are quite similar to nymphs of Myronides sp. "Peleng". But the nymphs of Myronides sp. "Peleng" have white antennae tips

_________________

Eggs

  • about 3,5 x 2 mm
  • a net-like, light structure on the surface, with dark dots

_________________

Food Plants

  • nymphs and adults feed easily on bramble (Rubus sp.)
  • they also like firethorn (Pyracantha sp.) - (thanks to Kristien Rabaey for this information)
  • other plants that they feed on: raspberry (Rubus idaeus), oak (Quercus sp.), Maple (Acer sp.), dogwood (Cornus sp.), strawberry (Fragarius sp.) (info by Simona Inches, Switzerland)
  • this seems to be a rather polyphagous species
  • firethorn (Pyracantha sp.) (Philippe van der Schoor, pers. comm.)

Defensive Behaviour

  • when being touched, males and females often try to escapeby letting themselves drop to the ground, where they remain still or crawl away
  • when being hold - they try to escape the grip and walk away

Breeding Notes

  • an easy to breed and very nice species
  • incubation in high humidity (HH-incubation method) yields good hatching ratios (about 70% in my culture)
  • incubation time at room temperatures (20 - 23°C) is about 3 - 4 months
  • 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 bottom of the cage helps raising humidity
  • nymphs can be kept in a Faunabox (or similar cage)
  • move nymphs to a bigger cage as they grow bigger
  • I have never sprayed nymphs or adults of this species with water
  • male will be adult after about 2,5 months (at room temperatures), females after about 3 months
  • males do not permanantly stay together with their female after mating
  • females start to lay eggs about 6 weeks after their adult moult
  • about 25 to 30 eggs per week
  • eggs are just dropped to the ground
