A prominent dark spot is usually present near the middle of the wing. The hind wings are much lighter colored, with a broad dusky baud around the outer margin enclosing a large light spot near the middle. The damage done by the Corn Worm is chiefly to corn in the ear. The caterpillars gnaw through the husk and devour the kernels. Their injuries cause more or less sap to exude, which, fermenting, often molds and spoils the entire ear. Tomatoes are often found with the caterpillar eating inside of the fruit. Ploughing infested fields very late in the fall to break the cocoons of the hibernating pupae and thus expose them to the killing influence of the frost will do much toward keeping this insect in check. The caterpillars in infested ears of corn should be sought for and destroyed. THE RED HUMPED APPLE TREE CATERPILLAR. (Edemasia concinna (S. & A.). This insect is a common one nearly every year, but was more than usually abundant during the past Fig. 9.—Red Humped Apple Tree Catekpillar. (After Saunaers.) The eggs are deposited in a cluster of a hundred or more on the under side of a leaf of the food plant during July. The caterpillars.
