Stick insects:
Order: Phasmatodea- meaning ghost (Greek)
Largest insects up to 250mm
50 species
Feed only on plants (Phytophagus)
Some species has wings for flight- colorfull wings - also used to deter predators
Lays a single egg at a time- some species lay 100 eggs in 3 months
Eggs look like seeds and are simply dropped on ground.
Some species eggs has a removable part (capitilum) Ants carries eggs to thier nest and eat the capitilum.
This help to disperse the eggs and protect them against fire
They have a hemimotabolic life cycle and the nymphs look like the adults (12mm) They can shed their legs if theartend by predators and regrow them later - Adults can't regrow legs..
When you encounter a stick insect it is likely to be a FEMALE, because they reproduce by PARTHENOGENESIS
Vigin birth- Sterile eggs are laid and they hatch into fertile young stick insects

Depending on the definition there's actually up to 3000 species :big_eyes:

The biggest?

From Wikipedia (and other source corroborate)

Quote:
The stick insect Phobaeticus chani or Chan's megastick is the longest known insect, with one specimen held in the Natural History Museum in London measuring 567 millimetres (22.3 in). This measurement is however with the front legs fully extended. The body still measures an impressive 357 millimetres (14.1 in).

Named after amateur Malaysian naturalist, Datuk Chan Chew Lun, only six specimens are known, all originating from the State of Sabah in Borneo. Very little is known about its biology, but there is speculation that it lives in the canopy of the rainforest, making it especially hard to find.


Fascinating thing this stick insect!! :big_eyes:

Quote:
It lives high up in the rainforest canopy of Borneo, its eggs have tiny wings so they can glide from one tree to another, and now it has officially entered the record books as the longest insect species alive today.


(From here)

Nice to learn new things like this.

Rayno would like to know if anyone can tell him what sort of stick insect this is. No macro needed, it was HUGE! :shock: :lol:
Seen in Croc bridge camp a few days ago.

That's not a stick insect!

Its a tree insect!!! :big_eyes: :wink:

Certainly the largest I have seen, though not the largest on record, which I believe is almost 30cm?

Great sighting! :thumbs_up:

Spook, :thumbs_up:

Thank you, Imberbe. {from a very chuffed Rayno 8) }
He's just marched into my office, ruler on hand and feels confident that "his" gogga was about 25cm long. :lol:
