General Notes

  • 2011 – taxonomical aspects of this species are being examined by
             Joachim Bresseel (Belgium), and he will also describe this species
  • 2012 - first successful culture by Bruno Kneubuehler
  • 2012 - this species has been distributed as Clitumnini sp. "Tam Dao“

_________________

Origin

  • Joachim Bresseel (Belgium) and Jérôme Constant (RBINS) found this species in July 2011 in the Tam Tao National Parc, Vietnam (No. 89, "Clitumnus sp.2", Vietnam, 2011)

_________________

Females

  • medium sized phasmids
  • about 12 – 14 cm long
  • coloration is consistent amongst females (F1)
  • body is glossy green with few dark brown areas
  • few small white dots on the thorax
  • white-black markings on the forehead
  • thin black stripe on the side (laterally) of the metathorax
  • legs are glossy green with some ligher green rings
  • antennae short and light brown
  • no wings (apterous)

_________________

Males

  • gracile, thin and pretty phasmids
  • about 10 – 11 cm long
  • head, prothorax, legs joints and abdominal ending are grey-brown
  • meso- and metathorax are blue-green
  • legs and abdomen are red-brown
  • long, thin legs
  • antennae are dark and about half the length of the forelegs
  • no wings (apterous)

_________________

Nymphs

  • about 15 mm (L1)
  • very short, brown antennae (L1)
  • yellow-green (L1)
  • by L2 it is quite easy to draw a distinction between ♀♂ (by the naked eye)

_________________

Eggs

  • rather big
  • about 6 x 3 mm
  • llight to darker brown
  • longish, flattish – with an idiosyncratic form
  • big capitulum on top of the egg lid (operculum)

_________________

Food Plants

  • bramble (Rubus sp.)
    is very well accepted by freshly hatched nymphs, older nymphs and adults
  • no other food plants have been tested by me (so far)

_________________

Behaviour

  • nymphs as well as adults are passive during the day and they usually feed during dawm / night
  • a defensive spray has not been observed
  • matings occur during the night and couples stay together for a few hours only

_________________

Developement

  • incubation time (HH-incubation on slightly damp sand at 20 - 23 °C) is about 6 months  (F1)
  • spread some dried  (!) moss over the eggs - this will make it much easier for the nymphs to hatch unscathed and it also reduces mould growth to some extend
  • hatching ratio in F1 was very high (> 50%)
  • males and females will be adult after about 3 (at 20 – 23°C)
  • females start laying eggs after about 2 – 3 weeks
  • eggs are flinged away - with a swing of the abodmen
  • about 35 – 45 eggs per female and week
  • adults can live for several months

Breeding Notes

  • my general notes on how to breed phasmids are a integral part of this care sheet ...
  • it is very easy to breed this species
  • keep the nymphs in a cage with good ventilation, but take care that the humidity does not drop too low
  • a constantly wet paper towel on the floor of the cage helps raising humidity
  • a humidity level of about 60+ % rH (for adults) and 75+ % rH (for nymphs) seems to be fine

  • nymphs can be kept in a Faunabox (or similar cages)
  • move nymphs to a bigger cage as they grow bigger
  • a cage of at least 30 x 30 x 30 cm should be provided for 3 - 4 couples of this species (or considerably larger if the cage also contains other species !)
  • generally I advise to keep different phasmid species seperately (unfortunately, overcrowed cages are still too common ...)
  • I have never sprayed nymphs, adults or their cage 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
