General Notes

  • no synonyms
  • for some time (1935 to 1998) D. verrucosus has been seen as a synonym of Dares ulula (Westwood 1859)
  • verrucosus means „warty“ or „tubercular“

_________________

Culture History

  • has been in culture since 1984

_________________

Origin

  • Jonathan Cocking collected this species in July 1984 in Sepilok near Sandakan (Sabah, Borneo)

_________________

Female

  • small, very sturdy and compact phasmids
  • about 4,0 to 4,5 cm
  • dorsal side is tubercular and light to mid brown
  • ventral side is beige to light brown coloured
  • antenna consists of 25 segments, first segment (Scapus) flat, with 1 to 2 minute teeth outside

_________________

Male

  • small, slim and spiny phasmids
  • about 3,5 to 3,8 cm
  • contrasty coloration
  • basic colour usually beige with mainly blackish-brown patternings
  • middle and hind femurs black
  • head, meso- and metathorax with characteristic pairs of spines (dorsally)
  • a pair of spiny extensions on each abdominal segment (exept the first abdominal segment)
  • antenna consists of 23 segments

_________________

Nymphs

  • color of older nymphs is often stronger and more contrasty than the adults
  • regularly with a pair of white spots at the base of abdomen – which is typical for most  Dares species

_________________

Eggs

  • almost ball-shaped - 3,5 x 3,8 mm
  • spotted
  • dark grey to dark brown
  • 0,3 mm long, creme-white, curved tiny hairs

_________________

Food Plants

  • Bramble (Rubus spp.)
    is well accepted by nymphs and adults. But in spring they do not like the fresh leaves. Therefore one should collect stems with  leaves from the previous year
  • other Rosaceae - like hawthorn (Crataegus spp.), firethorn (Pyracantha spp.) und strawberry (Fragaria spp.)
  • Betulaceae - like hazelnut (Corylus spp.)
  • Fagaceae – like oak (Quercus spp.), beech (Fagus spp.)

_________________

Behaviour

  • nymphs and adults let fall themselves if disturbed, and then remain motionless for some time
  • while they remain motionless,  frontlegs are streched out ahead, midlegshindlegs are bent and close to the body, and hindlegs are strecked out backwards
  • females will lay 1 to 3 eggs per week
  • females need a substrate in which they lay their eggs
  • often they lay eggs also on other things in the cage like branches or bark - especially if their surface is craggy or covered by moss

_________________

Development

  • incubation time at room temperatures (20-23°C) is about 3 to 5 months
  • male will be adult after about 10 months, females after about 12 months
  • females can live about 5 years

_________________

Breeding Notes

  • easy to breed
  • incubation on slightly humid substrate (sand, Vermiculite ect)
  • breeding in very small cages with high humidity and some small ventilation openings is possible
  • humidity can be kept high with a constantly wet paper towel on the ground or by carefully wetting the substrate
  • nymphs and adults can be sprayed with water
  • as an egg-laying substrate I use a humus-sand-mix (with some coconut fibres), which is covered by moss (Sphagnum sp.) to reduce the danger of going mouldy and to adjust the humidity easily
  • eggs can be incubated on the substrate where they have been laid – or they can be collected and incubated seperatly
