Fall, Web-wobm Moth, an insect which un- ">' dergoes "complete metamorphosis;" o, larval form; this QUieSCeut Or DUDal 6, pupal form; c, adult or moth form. \ V r stage is called -pupation, or, the larva is said to pupate. These terms are frequently used hereafter. During this stage the insect takes no food, but is un- dergoing within its protecting case the marvelous changes in bodily structure which result in the issuance of the beautiful white- and rose-tinted moth, with its four wings and deli- cate sucking tube, from a chrys- alis which was formed by the pupation of the crawling, bit- ing, sluggish, green Maple- worm. The fourth stage is that of the adult ; the one real mission of wliicli is the perpet- uation of the species. As be- fore said, no injury is done by the adult moths and butterflies, nor by the four-winged hymen- opterous insects, (the Raspberry- and Rose-slug Saw-flies,) but many beetles are seriously injurious in the adult stage, as the Cucumber Beetle and others. All insects, however, do not undergo such a complete metamor- phosis, and four distinct stages cannot be made out in the lives.
