Agricultural Experiment Station; Agriculture -- New York (State). Rural School Leaflet 887 down from the sixth, seventh, eighth, and ninth segments, counting from the head. And, lest he fall off, he has on the last segment of the body a clasping foot, called the prop leg. On each side of each segment, except the first, there may be seen a breathing pore, or spiracle, through which air is drawn into the insect's body to purify the blood. Our fully grown, uneasy caterpillar finally finds snug quarters on the underside of some board or stone, and there it spins a thick cocoon, shaped like a slender jug without a handle. The silk of the cocoon is white and with it is mixed a yellowish white powder. Once within the cocoon the caterpillar sheds its skin, and it now appears as an oblong, smooth object, very little like a caterpillar in shape. This is its pupa state, and during this time it develops within itself its wings and various other adult organs. In about three weeks the pupa skin bursts open and the insect crawls from the cocoon, a pretty moth with dull yellowish or reddish brown wings and with two whitish stripes across each front wing. The adult moths usually appear the last of June or the first of July and soon afterward the mother moth lays her eggs. There are several ways of protecting our orchards from the ravages of this caterpillar. A common way is by destroying the webs with a torch. It is neces- sary to apply the torch on dark or stormy days, so that the little inmates may be destroyed with their tent. But nowadays we trust to spraying. We must spray as soon as the apples are out of blossom for the codling moth and the apple scab, and this spray settling on the leaves usually kills the apple tent-caterpillars very early in their Apple-tree tent-cater- pillars LESSON
