BUT'TERFLY, noun [from the color of a yellow species.]
Papilio, a genus of insects, of the order of lepidopters. They have four wings imbricated with a kind of downy scales; the tongue is convoluted in a spiral form; and the body is hairy. The species are numerous. Butter-flies proceed from the crysalids of caterpillars; caterpillars proceed from eggs deposited by butterflies; they then change into crysalids, which produce butterflies, which again deposit their eggs.
