When do caterpillars turn into butterflies?

Young insects develop in two main ways. Butterflies, bees and beetles, go through a process called metamorphosis. This means that their eggs hatch into larvae or caterpillars. Later these become a pupa or chrysalis, within an imago, or an adult insect, develops. The larvae may live in a different habitat from the adult and require different foods.

In species such as grasshoppers and locusts, the young that hatch from eggs look rather like small adults, and are called nymphs. As they grow, the nymphs shed their skins, looking more and more like adults each time.

Fact file:

The wings of a bee or wasp can beat as many as 250 times per second during flight. The wings of midges can beat as many as 1,000 times per second – which accounts for the high-pitched whine that these tiny insects make.
