Spring and summer broods eclose in a matter of weeks; autumn broods enter a state known as diapause and emerge the following spring. How the pupae know when to eclose early or hibernate is not yet fully understood, though research suggests day length during the fifth larval instar plays a major role, as well as cooling temperatures.

As the larva grows, it moults four times in its five larval stages, after which the mopane worm is considered most desirable for harvesting.
Butterflies need specific plants, called host plants, where they can lay their eggs and caterpillars hatch. Not all caterpillars will become butterflies, of course, because some are eaten by birds ...
