INJURIOUS TO MEL0N8, CUCUMBERS, SQUASH, ETC. 395 Life History.—The moths appear soon after their food-plantsstart growth, from mid-April along the Clulf Coast to June 1st,in New Jersey, and late June or early July in Connecticut. Theyfly only in the daytime, and their clear wings and brightly markedbodies give them a close resemblance to large wasps. The eggsare laid on all parts of the plant, but chiefly on the stems, par-ticularly near the base. The oval egg is of a dull red color andabout one-twenty-fifth inch long. The moth deposits her.

The young larva entersthe main stem and tunnels through it, and often enters the leaf-petioles l^ranching from it. It is a soft, stout, whitish caterpillar,with a small black head, and about one inch long when full larvse reach maturity in about four weeks and then enterthe earth, where they make tough silken cocoons, coated withparticles of earth, an inch or two l^elow the surface. In theSouth the larvae transform to pupae from which a second generation 396 INSECT PESTS OF FARM, GARDEN AND ORCHARD of moths emerges in late July, but in the North the larvse hibernatein the cocoons over winter, and transform the nekt spring. Thepupa is about five-eighths inch long, dark brown, and witha horn-like process on the head between the eyes. By the aidof thi
