Thefemale moths lay the eggs in the evening on tomatoplants, where they soon hatch into green worms thatfeed voraciously on the foliage. These caterpillarsgrow rapidly, and in a few weeks become three incheslong and nearly as thick as a mans finger. Theyare light green, with several oblique, whitish stripesalong each side of the body: sometimes brownspecimens are found. Early in September, in theNorthern States, these caterpillars complete theirlarval growth, and burrow into the ground somedistance, where they form oval cells in the soil, shedtheir larval skins, and change to pupse. The pupa 166 INSECTS AFFECTING THE TOMATO. or chrysalis (Fig. 85) is of chestnut-brown color, witha long and slender tongue case bent over like thehandle of a jug. They remain in this state untilthe following summer, when they come forth as. am Fig. 85. Pupa of Tomato Worm. moths. Besides the leaves, the caterpillars often feedupon the green fruit of the tomato, as well as uponthe foliage of the potato and tobacco. There is another species similar to this one, confounded with it. The life-history andhabits of the two are much alike. The moth of theother one is called the Carolina Sphinx (Phlegethon-tius Carolina). In the Southern States, and even asfar north as central Ohio, there are two broods eachseason. The Tomato Worm is subject to the attacks of asmall, four-winged, black fly that deposits eggs be-neath its skin along the back. The eggs hatch intolittle maggots that absorb the body juices of theworm, developing at its expense, and finally comingout upon its back, where they spin white, silkencocoons (Fig. 86), within which they change to afterward they again change to flies tha
