Asprenas femoratus "Koghi"
(by Bruno Kneubuehler)

 

General Informations

  • this culture was formerly known as Asprenas sp. "apterous, Koghi"
  • ID by Frank Hennemann (DE)
  • provenience: Mt. Koghi (New Caledonia)
  • collected by a local hobby entomologist in January 2014
  • different phasmid taxonomists suggest that this might be Asprenas impennis, a definite ID is not yet available
  • F1 CB culture by Bruno Kneubuehler (20145)
  • further taxonomical informations ➤ phasmida.speciesfile.org
  • this is a pure culture, and serious breeders are asked to not mix it with cultures of a different provenience

Females

  • sturdy, medium sized phasmids
  • body length 10 - 11 cm
  • brown mottled or green-brown
  • short antennae
  • long "ovipositor" (subgenital plate, supraanal plate)
  • spines on thorax and head
  • black cheeks

Males

  • rather sturdy too
  • 8 - 8.5 cm
  • brown with greenish legs
  • spines on thorax, head and legs
  • black cheeks

Food Plants

  • bramble (Rubus spp.)
    very well accepted by nymphs and adults
  • hazelnut (Corylus avellana)
    very well accepted by nymphs and adults
  • Salal (Gaultheris shallon)
    very well accepted by nymphs and adults

Breeding, Behaviour

  • active mainly during the night, though males are sometimes active during daytime too
  • they try to drop to the ground and / or crawl away when they feel threatened
  • eggs are stuck into a suitable substrate, e.g. humid peat
  • a sand-filled (about 3 cm high), shallow box is also well accepted for oviposition. But the box in a corner of the cage. Eggs have to be sieved out of the sand once per week (to prevent that they dry out)
  • 30 - 40 eggs per clutch
  • 1 clutch of eggs every 1 - 2 weeks
  • incubation (HH-method on slightly damp sand) about 3 - 4 months at 20 - 23 °C
  • nymphs hatch during the night
  • a higher humidity of 75 - 80 % rH is needed
  • one can spray them regularly with chlorine-free water, but the water should dry up again
  • very easy to breed in my experience

Basics of breeding phasmids

  • only one species per cage, overpopulation is one of the main reasons for breeding failures
  • keep nymphs seperate from the adults
  • choose the cage big enough, when in doubt it is better to choose a cage too big than too small
  • a ventilator often supports breeding results
  • provide enough light, but avoid direct sunlight (overheating)
  • try to keep temperatures below 25°C
  • a nocturnal fall of temperature is healty for the phasmids
  • do not spray too much, phasmids are no fish ! The spray should dry up again
  • minimize disturbances (loud music, commotions, light at night, ect.) minimal
