General Notes

  • 2010 - Mnesilochus sp. "Mt. Halcon" imported and bred for the first time by Bruno Kneubuehler
  • 2010 - the taxonomic position of this species is subject to current research by Joachim Bresseel (Belgium)



  • Mnesilochus sp. "Mt. Halcon" has been collected on Mt. Halcon (Mindoro island, Philippines) in April 2010



  • very typical phasmids
  • about 10.5 - 11.5 cm long
  • colouration is very variable amongst females
  • mainly different combinations of light and dark brown
  • there are very light and very dark specimens
  • some females have a smooth abdomen, while others have small, spine-like scales on their back (dorsal, on several abdominal segments) - and few specimens do have a bigger, bulging expansion at the dorsal joint of 5th / 6th abdominal segment
  • prominent expansions and a light-coloured band on the midlegs' thighs (mesofemora)
  • two small, forward-pointed spines on the head - which sits on a ridge across the head
  • whole body surface is strongly garnulated - giving them a very bark-like appearance
  • antennae are bit shorter than the forelegs



  • thin and very typical for the genus
  • about 8 - 9 cm long
  • colouration of the males is uniformly brown
  • body surface is weakly granulated
  • two prominent, forward-pointing spines on the head
  • antennae slightly longer than the forelegs
  • no expansions on the legs


Nymphs (L1)

  • dark brown
  • about 1,5 cm
  • antennae slightly shorter than forelegs
  • the spines on the head are already visible in L1
  • by L2 it is possible to distinguish sexes by the presence or absence of the male's poculum
  • easier differentiation by L3 - by then females develop clearly visible expansions and a light-coloured band on the midlegs' thighs (mesofemora)



  • about 4 x 2 mm
  • dark brown with some light brown spots
  • light brown capitulum
  • light brown microphylar plate
  • porous, not shiny surface


Food Plants

  • nymphs and adults feed very well on bramble (Rubus sp.)
  • at least nymphs do also feed well on privet (Ligustrum sp.)



  • nymphs as well as adult specimens show a passive defence behaviour - which is very typical for the genus
  • they almost entirely rely on their camouflage
  • rarely they try to escape by crawling away, just to freeze again after a short distance
  • regularely they drop to the ground when they feel threatened, where they freeze with tightened legs
  • matings last only for a short time, males do not stay together with the same female for a longer period


Breeding Notes

  • a very easy to breed species
  • incubation with the HH-method (on slightly damp sand) yields a good hatching ratio
  • some moss spread over the eggs reduces mould growth and strongly facilitates successful hatching
  • incubation time at room temperatures (20 - 23°C) is about 4,5 months
  • hatching ratio is very high (75+ %)
  • 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 floor of the cage helps raising humidity
  • move nymphs to a bigger cage as they grow bigger
  • I have never sprayed nymphs or adults 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
  • males will be adult after about 3 months (at 20 - 23°C), females after 3.5 - 4 months
  • females start to lay eggs after about 2 - 3 weeks
  • eggs are just dropped to the ground
  • about 7 eggs per week and female
