General Notes

  • the taxonomic position of this species is subject to current research by Oskar Conle and Frank Hennemann. Results on this should be available soon and will also be published here
  • 2008 - first successful culture of this species by Bruno Kneubuehler
  • 2010 - distributed to other breeders by the false name Isagoras sp. "Los Banos"
  • 2015 - the correct name for this species is Isagoras sp. "San Miguel de Los Bancos"

_________________

Origin

  • 2008 - Horst Kaech (Ecuador) found this species in April in Pachijal (San Miguel de Los Bancos , Pichincha, Ecuador)

_________________

Female

  • 7 - 7,5 cm long
  • colouration is variable - brown, brown-grey or brown-green
  • females can fly very well too

_________________

Male

  • small and thin phasmids
  • about 5 - 5,5 cm long
  • colouration is as variable as in females
  • they fly very well, also over longer distances (at least several meters)
  • males have a short life span, only 4 - 6 weeks (with some exceptions)

_________________

Nymphs (L1)

  • green-brown
  • antennae are longer than the fore legs

_________________

Eggs

  • if the eggs were not yet in touch with water, then they have a smooth surface
  • soon after they come in contact with water, they develop a furry appearance
  • about 2,5 x 1,5 mm
  • dark brown
  • surface is matt

_________________
 

Food Plants

  • nymphs (from L1) as well as adults feed very easily on bramble (Rubus sp.)
  • considering the small size of this species,  they can eat quite a lot
  • in Ecuador also plants of the family Piperaceae were accepted as food plants

_________________

Defensive Behaviour

  • if young nymphs feel threatened, they can jump from their resting place and fall to the ground
  • also adult males and females try to escape as soon as they feel threatened (opening the cage door might already trigger this behaviour)
  • males can fly for quite a distance
  • females (especially when full with eggs) usually fly only for a short distance
  • upon landing, they freeze quickly

_________________

Breeding Notes

  • an easy to breed and active species
  • as it is a species with a hectic behaviour which quickly tries to escape, changing their food plants can tax the patience of the breeder
  • incubation: HH-incubation method on slightly damp sand yields good hatching ratios
  • hatching ratio in the 3rd generation was more than 50 %
  • incubation time at room temperatures (20 - 23°C) is about 3,5 months
  • 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 bottom of the cage helps raising humidity
  • if the cage of the nymphs is overcrowded, then problems during moulting are quite frequent (and sometimes fatal)
  • nymphs and adults can be kept in a Faunabox (or similar cage)
  • move nymphs to a bigger cage as they grow bigger
  • I have never sprayed nymphs or adults with water
  • males will be adult after about 2,5 months (at 20 - 23°C), females after 3 months
  • females start to lay eggs after about 2 weeks
  • eggs are just dropped to the ground
