In from eight to sixteen days after the chrysalis is formed the butterfly emerges. In Florida there are usually four broods of the butterflies in the course of the summer, the last brood wintering in the chrysalis state, from which the butterflies emerge in April. The caterpillar, which is commonly known as *^ the orange dog" in Florida, devours the foliage of orange-trees, sometimes seriously injuring young trees by stripping them bare. It may easily be subdued by hand-picking, as its large size and singular appearance promptly lead to its discovery. Within the past ten years this butterfly has extended its range very much, and it is now comparatively common throughout the Northern and Western States, and in the warmer parts of Canada. In the North it feeds chiefly on prickly ash, Zanthoxylum Americanum, No. 240.—The Orange Basket-worm. Platoeceticus Gloveri Packard. During the month of February this insect is found upou the orange-trees in different parts of Florida. The larva forms an oblong-oval case of a paper- like substance, interwoven with bits of leaves or bark, as shown in Fig. 392; within this it lives. When full grown, it is a little over half an inch long, thick and fleshy, and varies in color from light brown to a much darker shade. The head is marked with dark and light wavy lines, and is protruded from the case, along wath the anterior segments, when the larva is feeding or moving from place to place. The case of the female is about one-fourth lar2:er than that of the male. Both of these are shown in the figure.
