Stick Bug (Eurycnema goliath) (PSG-14)
The following is a chart that I made to help shed
some light on the growth rate of each phasmid, and
eventually gather enaph information to compare and
see if it differs between Males and Females and
between other species. This also tells me that at
L4- L5 E. goliath should be on Eucalyptus or other
highly nutritious plat as their exoskeleton will
almost double in size!
|The following is information on the Male E.
goliath. I was not able to record the length
of L1- L3 nymph, so hope to do so next time
|Stage of the Male Phasmids:
||Current length of particular Instar:
||E. goliath growth rate:
|| 76mm long.
||46.05% longer then at L4.
||20.72% longer then at L5.
||13.43% longer then at L6.
E. goliath are the second largest stick insect
in Australia. They should be kept at 20- 25°C, although
can be kept at as low as 17°C for short amount of
time. Ova takes 5- 6 month to hatch. Nymphs take
4- 6 month to mature. They rarely eat Bramble, although
some times they will still accept it. Eucalyptus
is usually quite easy to come by during summer time,
from Garden Center. It usually is sold for under
$5.00 per 2 feet long tree.
Females: get 17- 20cm long, with 2.5cm long
Males: get 13- 15cm long. Males become adults
on the 7th molt.
Diet: Eucalyptus, Bramble
(rerely) , Acacia, Millepertuis (like Millepertuis
