Moths of the Limberlost . o the moth, thecaterpillar is made up of three parts, head, thorax, andabdomen, with the organs and appendages of after moulting the head appears very large,and seems too heavy for the size of the body. Atthe end of a feeding period and just previous to anothermoult the body has grown until the head is almost lostfrom sight, and it now seems small and insignificant; sothat the appearance of a caterpillar depends on whetheryou examine it before or after moulting. The head is made up of rings or segments, the same asthe body, but they are so closely set that it seems to be aflat, round, or pointed formation with discernible ringson the face before casting time. The eyes are of so sim-ple form that they are supposed only to distinguish hghtfrom darkness. The complicated mouth is at the lowerpart of the head. It carries a heavy pair of cutters withwhich the caterpillar bites off large pieces of leaf, a firstpair of grinders with which it macerates the food, and a 58. MOTHS OF THE LIMBERLOST second pair that join in forming the under lip. Thereis also the tube that connects with the silk glands andends in the spinneret. Through this tube a fluid isforced that by movements of the head the caterpillarattaches where it will and draws into fine threads that atonce harden in silk. This organism is sufficiently devel-oped for use in a newly emerged caterpillar, for it canspin threads by which to drop from leaf to leaf or to guideit back to a starting point. The thorax is covered by the first three rings behindthe head, and on it are six legs, two on each remainder of the caterpillar is abdominal and car-ries small pro-legs with which to help it chng to twigsand leaves, and the heavy anal props that support thevent. By using these and several of the pro-legs immedi-ately before them, the caterpillar can chng and erect thefront part of the body so that it can strike from side toside when disturbed.
