A walkingstick (палочник), also called a stick insect or a stick-bug, lives in all continents except Antarctica. There are a lot of them in the tropics and subtropics.

Their life stages are: eggs, wich are small, oval and hard-shelled, nymphs (they resemble adults but differ in color and size), adulthood (they reach maturity after 3 months to a year).

Walkingstick insects resemble green or brownish sticks or twigs, which gives them natural camouflage and an effective defense against predators. Female stick bugs are generally larger than males. Most male stick species have wings.

They eat tree leaves and other green plants.

Stick insects can live from a few months to up to three years, depending on the species.

Amazing facts:

- A few species are even able to change their pigmentation to match their surroundings like a chameleon.

- Stick insects very in size from 1.5 centimeters to about 60 centimeters in length.
