General Notes
- Joachim Bresseel does taxonomical work on this species and genus
- there are various similar Necrosciinae species which are part of this new genus and are going to be described by Joachim Bresseel
- their appearance is very similar to Necrosciinae sp. “Cat Tien”, suspicion of relation
_________________
Origin
- Con Dao National Park, Con Dao Archipelago, Vietnam
_________________
Females
- 70-80mm (body length)
- short winged (hind wings reach to the middle of the abdomen, approx. 30mm)
- colorful; head and wings in different brown shades
- body dorsal green and ventral yellow
- membranous part of the hind wings is deeply violet
- the hind wings drift apart
- long antennae
- legs are turquoise
_________________
Males
- 60-65mm (body length)
- wings reach ¾ of the Abdomen
- colorful; head and wings in different brown shades
- body dorsal green and ventral yellow
- membranous part of the hind wings is deeply violet
- long antennae
- legs are turquoise
- are able to fly, but rarely do so

Nymphs
_________________
Eggs
- hatch after 3-4 months
- short posterior spine
- about 4.5 x 2 mm (including spine)
- elongate-oval
- spotted
- often placed in clusters
_________________
Food Plants
- Bay laurel (Laurus nobilis)
is accepted well. - Many willow species (Salix sp.) are accepted well; especially crack willow (Salix fragilis)
- often accept crack willow (Salix fragilis) better than Laurus nobilis
- I tried some different plants, but I did not find any further accepted foodplants
- probably Salal (Gaultheria shallon) coated with Laurel also might work
_________________
Behaviour
- both, nymphs and adults, are rather active during the day
- mostly active during the night
- if small nymphs are touched, they use thanatosis.
- older nymphs and adults (especially adult males) try to drop to the ground or crawl away, if being touched
- an odorous defense spray is used
- mating and deposition of eggs occurs during the night
_________________
Developement
- incubation time (HH-incubation on slightly damp sand at 20 - 23 °C) is approx. 3 months
- high hatching ratio
- I spread some dry moss over the eggs to support the process of hatching
- females start laying eggs after about 2 – 3 weeks
- eggs are sticked into different substrates
- I offer floral foam for the deposition of the eggs and it was accepted very well
- they lay about 10-15 Eggs per week
- male and female live several months (5-7)

Breeding Notes
- keep them in good ventilation with moderate humidity (60%+ rH)
- I have never sprayed nymphs or adults with water, but I have watered the soil once a week
- a wet towel paper could also be enough to keep up the humidity
- keep the nymphs in a cage that offers no chance to escape; for example a prepared faunabox works
- when the nymphs grow bigger, move them into cages of appropriate size
- I generally keep species separately to avoid cross-breeding and overcrowding
- choose cages which are high enough to avoid mistakes at moult and ensure that individuals have no chance to moult in places that would lead to miss-moult
