Papillon is butterfly in french. Butterflies, because of their beauty and mystique, are our most visible
insects. Adults butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. Butterflies are grouped by specific shared characteristics.

The butterfly life cycle has four distinct stages; egg, caterpillar (larva),chrysalis (pupa), and adult. This four-stage development is called complete metamoqhosis (metamorphosis means change in form) and is shared with other insect orders such as Coleoptera, Diptera, and Hymenoptera. It contrasts to the three-stage incomplete metamorphosis of egg, nymph, and adult characteristic of Hemiptera, Odonata, Orthoptera, and several other orders.

A female butterfly can lay a large number of eggs--over 1,000 in the buckeye, for example. Clearly, if all of these eventually produced an adult, the earth would soon be overrun by millions of these beautiful animals. Momentarily spectacular as that might be, it would soon cause problems in the ecological scheme of things, particularly as larval food plants were consumed. There is little danger of this happening. Butterflies, in all four life stages, are beset with parasitoids, predators, and diseases that limit their numbers.
