n. any of a number of winged insects of the order Lepidoptera having long slender bodies and four colorful wings; butterfly stroke (Swimming); person who is in constant pursuit of pleasure

A butterfly is an insect of the order Lepidoptera. Like all Lepidoptera, butterflies are notable for their unusual life cycle with a larval caterpillar stage, an inactive pupal stage, and a spectacular metamorphosis into a familiar and colourful winged adult form. Most species are day-flying so they regularly attract attention. The diverse patterns formed by their brightly coloured wings and their erratic yet graceful flight have made butterfly watching a popular hobby.
