general informations

  • this species has been cultivated successfully for the first time by Jan Meerman (Belize, 2006) and Bruno Kneubühler  (2007)
  • 2007 - I have distributed this species as Hypocyrtus scythrus to other breeders
     

origin

  • Jan Meerman (Belize) collected this species in 2006 in the area of Belmopan
     

females

  • sturdy, slow-moving insects
  • quite thick when ready to lay eggs
  • small, 7-8 cm long
  • wingless
  • many females have a protuberance on the dorsal mesothorax, which is often just two small spines, but occassionally becomes a prominent bump-like protuberance
  • colouration: different shades of brown, with some darker spots
  • body is rough-textured, not shining
  • antennae a bit longer than the fore legs
  • often females have small lobe-like expansions and small spines on the legs
  • prothorax is strongly granulated, head and mesothorax are slightly granulated
  • many females have a lobe-like expansion on the side of the 7th abdominal segment which can be quite prominent
  • a thin appendix of the subgenitalplate often exeeds the terminal abdominal segment
     

males

  • slim, slow-moving insects
  • small, 6 cm long
  • wingless
  • all males have a light brown to almost white spot on each side of the metathorax, close to the joint of the hind legs
  • prothorax (dorsally) and head rough-textured, rest of the body quite smooth
  • colouration: light brown when as young adults, dark brown when older, with some lighter brown patches. Sides of the mesothorax are reddish brown
  • antennae longer than the fore legs
     

eggs

  • barrel-shaped, strongly-granulated, dark brown eggs with hair-like structures
  • 5 mm long, 2 mm broad
     

breeding notes

  • incubation on damp sand, with springtails to prevent growth of mould
  • incubation at room temperatures (18-22 °C) takes 4-5 months
  • nymphs feed easily on bramble, cut edges of leaves for newly hatched nymphs
  • keep nymphs and adults at high humidity, yet provide their cage with sufficiant air ventilation
  • I do never spray the nymphs nor the adults, a damp paper towel provides enough humidity
  • this is a quite slow growing species - males mature after about 5 months, while females mature after about 7-8 months
  • they do not require a big cage, nor do they have moulting problems in even quite a crowded cage
  • as it is a slow-moving species, they do not eat a lot
  • females start laying eggs some weeks after their final moult, only about 4 eggs per week which just drop to the gound
