General Notes

  • described by Hennemann, Conle, Suzuki (2015) as Anchiale buruense
  • Etymology – in the greek mythology Anchiale (or Anhkiale) is the Titan goddess of the warmth of fire, and the wife of Hekateros
  • the genus Anchiale has been introduced by Stål (1875) with the type species Anchiale maculata (which has been described by Olivier in 1792 as Mantis maculata)
  • the genus Ctenomorphodes is a synonym for Anchiale
  • until 2012 5 different Anchiale species are or have been in culture – see PSG list on Phasmatodea.com
  • Anchiale sp. "Buru" is most probably a new species (Frank Hennemann, per. comm. 2012)

Culture History

  • 2011 -  eggs of this species have been imported by Bruno Kneubühler
  • 2012 - first successful culture by Bruno Kneubuehler
  • 2012 - this species has been distributed as Anchiale sp. „Buru“
  • 2015 - this culture should now be called Anchiale buruense "Buru"

_________________

Origin

  • eggs have been collected in the 3rd quarter of 2011 on the island of Buru (Maluku Islands, Indonesia). More detailed informations on the location could not be obtained

_________________

Females

  • big, rather stout phasmids
  • about 15.5 – 16.5 cm long
  • coloration amongst females seems to be consistent, judged by only available two adult females
  • main coloration geenish-brown
  • several spines on the legs, especially the forelegs
  • small humps on the mesothorax (dorsally)
  • subgenital plate is well developed and reaches beyond the abdominal ending
  • angennae shorter than forelegs
  • long, broad cerci
  • wings are well develped, hind wings are about half as long as the abdomen
  • (closed) wings are reddish-brown
  • membranous part of hindwings (alae) is mottled grey-black

_________________

Males

  • medium sized, thin phasmids
  • about 9.5 – 10.5 cm lang
  • coloration is rather consistent amongst males (F1)
  • main color greenish-brown
  • dark areas on the head and legs
  • (closed) wings reddish-brown
  • head with interesting markings – makes them look like miniature Beagle Boys
  • 4 ocelli (simple eyes) are well developed and visible
  • antennae shorter than forelegs
  • small spines on the legs
  • several small humps, mainly on the mesothorax (dorsally)
  • long cerci
  • wings are very well developed
  • membranous part of hindwings (alae) is mottled transparent-black

_________________

Nymphs

  • about 13 mm (L1)
  • dorsally reddish-brown, ventrally greenish (L1)
  • very short antennae
  • red eyes (L1)
  • already in L3 it is quite easy to draw a distinction between ♀♂ (by the naked eye)

_________________

Eggs

  • about 3.5 x 2 mm
  • variable color – many are grey, others are grey-black or gray-brown
  • glossy
  • irregular, elongate
  • distinct, greenish capitulum is present on the operculum (egg lid)
  • micropylar plate is thin and long

_________________

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 and adults can react rather frantically when they feel threatened (like when being touched)
  • Especially the adult males drop down, wriggle about, try to fly away and freeze again after a few steps or a short flight
  • otherwise both nymphs and adults are passive during the day and feed during the night
  • a defensive spray has not been observed
  • males try to escape flying
  • females can not fly
  • females fling the eggs away  with a swing of their abdomen
  • mating coccur often during the night, males can stay with one female for up to some days

_________________

Developement

  • approximate incubation time (HH-incubation on slightly damp sand at 20 - 23 °C) is about  4 – 5 months  (F1). The exact incubation could not be determined, as the exact date when the eggs have been laid was unknown
  • 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 high (about 40%)
  • males will be adult after about 3 months (at 20 – 23°C), females after about 4 months
  • females start laying eggs after about 3 weeks
  • about 30 – 35 eggs per female and week
  • adults can live for several months

Breeding Notes

  • my general notes on how to breed phasmids are a substantial part of this care sheet ...
  • it is easy to breed this species
  • as the freshly hatched nymphs are already quite big, therefore the incubation container must be big enough
  • 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 like Faunarium)
  • move nymphs to a bigger cage as they grow bigger
  • a cage of at least 50 x 30 x 30 cm should be provided for 3 – 4 adult couples of this species (or considerably larger if the cage also contains other species !)
  • generally I advise to keep different phasmid species seperately (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
