PiG. 286. A squash stem cut open showing borers within. (Photo by Quain- tance.) eggs singly, and one individual has been observed to lay as manyas 212. They hatch in one or two weeks. The young larva entersthe main stem and tunnels through it, and often centers the leaf-petioles branching from it. It is a soft, stout, whitish caterpillar,with a small black head, and about one inch long when full larvie reach maturity in about four weeks and then enterthe earth, where they make tough silken cocoons, coated withparticles of earth, an inch or two below the surface. In theSouth the larvae transform to pupse from which a second generation 396 INSECT PESTS OF FARM, GARDEN AND ORCHARD of moths emerges in late July, l)ut in the North the larvae hibernatein the cocoons over winter, and transfoi-m the next spring.
