What is a stick insects life cycle?

The female stick insect mates (some can lay eggs without mating), sticking her eggs to leaves or just on the ground. She may lay any number between 100 and 1200. The eggs often look like plant seeds and sometimes take several months to hatch.

Baby insects (nymphs) look very like their parents. As each stage (or instar) of the insect grows big enough, it moults, that is, it sheds its outer skeleton, which it eats. After several moults it develops into the fully grown stick insect. Wings develop before the final moult. All males and the females of many species have wings, though usually only the males can fly.

Stick insects live about 12 months, sometimes longer when kept as pets.
