Stick insects are thin stick like insects which live where there is enough trees (with leaves) to eat. They can be either green or brown. Even though their not very pretty they are very interesting insect to study.

Eggs

Nymphs

Adult

This is the life cycle of a stick

insect.

It includes three stages- eggs, nymphs and

adults.

There are 3,000 species world wide and 101 species in Australia.

Stick Insects mainly live in the tropics. The three New Zealand species are in UK for the last 100’s of years and nearly in the south west of England

This diagram will give you a rough idea of which

countries stick insects live in.

The body shape of stick insects is usually cylindrical or flattened. They have 2 pairs of wings except species which are wingless. The wings consist of short, hardened forewings which protect a part of the larger, membranous, which mean transparent, hind wings.

Antennae are filiform, which means thin and tread like. They can either be short or long.

This is the wing anatomy of a Stick Insect:

Stick Insects have tiny holes along there bodies called spiracles. They use these holes are used to breathe.

Behaviour of a Stick Insect is very unusual for insect species.

Stick Insects make show rocking behaviour movements, and makes a rhythmic side to side move.

When a predator is around they drop off the branch they are on and pretend to be dead.
