_________________

Behaviour

  • nocturnal species, nymphs spend the day time in the branchs and under leaves of Gonzalagunia hirsuta. Adults fly very well on night.
  • matings can occur for a quite long time, even during the day, but males do not stay with the same female
  • when disturbed, nymphs and adults spray an odorant liquid which smells citronella. Adults also open quickly their orange wings in order to frighten and to fly away
  • when they escape, adults are attracted by the light
  • adults sometime move during the day
  • females lay between 2 and 3 eggs per day, which are thrown at random on the ground

_________________

Development

  • incubation time (on wet peat at 18-20°C) is between 4 and 7 months
  • males are adults (at 18-22°C) in 3.5 months, females in 3.5 to 4 months

Breeding Notes

  • I keep this species in a humid cage with a little bit of ventilation
  • nymphs can be kept with adults
  • I spray water on the ground about 2 times per week and sometime on the leaves
  • this species likes a high level of humidity
