There are lots of species of caterpillars and, to some extent, the number depends on the species - some have no legs at all. However, most caterpillars have 3 pairs of "true" legs and 5 pairs of "prolegs". Prolegs aren't really legs - they aren't jointed - but the serve a similar purpose. So most caterpillars can be said to have 16 legs (and hence 16 feet).

A caterpillar is not a species in itself. Caterpillars are the juveniles of (usually) butterflies and moths. After spending some time as caterpillars they morph into the adult form, in which they have the required six legs to be considered insects.
