Butterflies are part of the class of
insects in the order Lepidoptera, along with the moths. Adult butterflies have
large, often brightly coloured wings, and conspicuous, fluttering flight. The
group comprises the large superfamily Papilionoidea, along with two smaller
groups, the skippers (superfamily Hesperioidea) and the moth-butterflies
(superfamily Hedyloidea). Butterfly fossils date to the Palaeocene, about 56
million years ago.
Butterflies have the typical
four-stage insect life cycle. Winged adults lay eggs on the food plant on which
their larvae, known as caterpillars, will feed. The caterpillars grow,
sometimes very rapidly, and when fully developed pupate in a chrysalis. When
metamorphosis is complete, the pupal skin splits, the adult insect climbs out
and, after its wings have expanded and dried, it flies off. Some butterflies,
especially in the tropics, have several generations in a year, while others
have a single generation, and a few in cold locations may take several years to
pass through their whole life cycle.
