Dajaca napolovi "Ba Vi"   (CLP 817)
(by Bruno Kneubuehler)


General Informations

  • provenience: Ba Vi NP (Vietnam)
  • collected in June / Juli 2015 by Joachim Bresseel (BE) and Jérome Constant (BE)
  • ID and taxonomic evaluation by Joachim Bresseel (BE)
  • F1 CB culture in 2016 by Bruno Kneubuehler (CH)
  • further taxonomical informations ➤ Phasmida Species Files
  • this is a pure culture, and serious breeders are asked to avoid mixing this culture with similar populations from a different provenience. When spreading this culture to other breeders, then always use the full name with provenience
  • this culture has the number CLP 817  (Online Phasma Culture List)


  • sturdy, small species
  • body length 5.5 cm
  • mottled greenish-brown


  • slender, very small phasmids
  • body length 3.5 cm
  • mottled brown


  • freshly hatched nymphs with dark reddish-brown body, reddish legs and strongly banded anteannae
  • 11 mm
  • on how to distinguish between male and female nymphs


  • 4.5 x 2.5 mm
  • reddish-brown
  • glossy, hairy

Food Plants

  • strawberry (Fragaria)
    very well accepted by all stages nymphs and adults
  • best to start freshly hatched nymphs on strawberry leaves
  • bramble (Rubus)
    reluctantly accepted
  • Salal (Gaultheria shallon)
    very well accepted by L3+ nymphs and adults

Breeding, Behaviour

  • easy to breed
  • active mainly during the night
  • when they get frightened, then they can behave frantically
  • males stay their whole live with the same female
  • they have a white defensive spray, which smells similar to the Orxines macklottii's spray and somewhat punchend (peppery)
  • this defensive spray seems to be quite potent. I had a little cut on a finger, when I handled my D. napolovie "Ba Vi" (changing food plants). So some spray got into that wound - and it immediately burnt like hell. I don't wanna know how intensly it burns, if their spray gets in the eyes ...
  • eggs just drop to the ground
  • about 10 - 15 eggs per female and week
  • incubation (Cup-Incubation-method, on medium damp vermiculite) about 6 - 7 months at 20 - 24 °C
  • eggs can be covered by vermiculite (about 5 mm high), which makes it easier for the nymphs to hatch without getting stuck in the eggs shell
  • eggs of this species are not prone to get mouldy
  • nymphs hatch during daytime (around noon)
  • a humidity of about 65 - 75 % seems to be good enough for nymphs and adults
  • one can spray them regularly with chlorine-free water, but allow the water to dry up before spraying again
  • their poop gets mouldy very much, thus it is best that they are not kept too humid
  • males will be adult after 2.5 months (at 20 - 24°C), females after 3 months

Basics of phasmids breeding

  • keep only one species per cage, overpopulation is one of the main reasons for breeding failures
  • keep nymphs seperate from the adults, mainly to protect them during the crucial moulting phases
  • choose the cage big enough. When in doubt, too big is (usually) better than too small
  • a ventilator often supports good breeding results, as it seems to increase activity and feeding
  • provide enough light, but avoid direct sunlight (overheating)
  • try to keep day time temperatures below 25°C
  • a nocturnal fall of temperature is natural, and thus advantageous
  • do not spray too much, phasmids are no fish ! The water should dry up before you spray again
  • minimize disturbances (loud music, commotions, light at or during the night, opening up cages in the morning [often a moulting phase] ect.)
