1. n. In entomology: The popular name and also the technical specific name of a large silk-spinning moth, Attacus prometheus, or Telea or Callosamia promethea. The male moth is of a dark rich smoky or amber brown, the female of a lighter rusty or reddish brown. In both sexes the wings are crossed by a wavy whitish line near the middle, and have a wide clay-colored border. Near the tips of the fore wings there is an eye-like spot within a bluish-white crescent, and in the female there is an angular reddish-white spot, edged with black, near the middle of each wing. The eggs are laid in little clusters of five or six upon twigs in the spring. The larva or worm is delicate bluish-white with a faint pruinescence, with four black tubercles on the thorax. It feeds on ash, sassafras, wild cherry, lilac, maple, plum, poplar, birch, and other trees. The cocoon is oblong, dense, gray, and remarkable for the long tough band of silk which suspends it and which is securely wrapped around the supporting twig. Also promethea, promethia.
2. n. [capitalized] A genus of moths.
3. n. In ornithology, the Blackburnian warbler, Dendrœca blackburniæ: so named by Coues from the flame color of the breast.
