A caterpillar is a small creature with a long soft body and many short legs. It eats leaves, and later it changes into a butterfly or a moth. Children often call it a kind of worm, and it does look like one, but it is not a worm: it is the young form of those flying insects. Some caterpillars are hairy, some are smooth, some are brightly coloured.

Though actually, the English name probably comes from an old French name meaning “hairy cat,” which is a funny picture, not a science name. There is also a big machine company called Caterpillar, because a tracked vehicle crawls a bit like this creature. Same spelling; this entry is the animal.
