Butterfly
I love blue butterflies.
Butterflies are insects in the macrolepidopteran clade Rhopalocera from the order Lepidoptera, which also includes
moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group
comprises the large superfamily Papilionoidea, which contains at least one former group, the skippers , and the most recent analyses suggest it also contains the moth-butterflies.
Butterfly fossils date to the Paleocene, 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
entire life cycle.
