Fall ploughing has been recommended to destroy the chrysalids by turning them up, when they are likely to be either killed by exposure or devoured by birds. Hogs also are very useful in destroying this pest by rooting up the chrysalids and eating them. These insects have many natural enemies. A small mite, Nothrus ovivorus Packard (Fig. 63), destroys the eggs. A minute parasitic fly deposits her ^gg^ within the eggs of the canker-worm and destroys them. In the larval state they are preyed on by a small four-winged fly, a species of Microgaster, which, after having fed upon its victim to full growth, eats its way out, and constructs a small oval white cocoon attached to the body of the caterpillar. A species of Tachina, a two-winged fly similar to Fig. 46, No. 21, is also a parasite on these worms. Predaceous insects also feed upob them, especially the Green Caterpillar-hunter (Fig. 47), the Copper-spotted Calosoma (Fig. 48), and the Rapacious Soldier-bug, Sinea diadema (Say) (Fig. 64). The.
