Diagnosis. — Kernels of corn shelled or in the ear, grains of wheat, etc., showing a small, round hole; when a handful of the grain is thrown into water, some of the kernels (the attacked ones) float. Description and Life-history. — The adult form of the insect is a small moth about one-fourth of an inch in length, and about one-half an inch from tip to tip of expanded wings. As a larva or grub, during which stage the damage is done, it is found bur- rowing within kernels of various stored grains, eating out the inside starchy portion, and leaving only a shell. The moths fly about at night, and lay their eggs either on stand- ing grain in the field or on stored grain in bins and cribs. There are probably four or five broods each year in this State. The eggs are deposited at the base of the kernel, so that the larva or grub on hatching makes its entrance hole at the base. This hole is usually filled with excreta, so that it is not noticeable. The larva after some time changes into a quiescent pupa. Just before this. Fig. 24.
