Corn Earworm
 Corn Earworm - The corn earworm generally overwinters in areas from the southern part of the
state and southward. Normal prevailing winds will move the adults northward. The
first generation of corn earworms appears early in the growing season so they
provide little damage to green beans. The second generation that begins with
moth flights in late July, is usually larger and more serious doing most of its
damage in late August through September. The larvae vary in color from light
green to tan, brown, pink maroon or nearly black and have light and dark stripes
running the length of the body. Their body is covered by short dense microspines.
The small larvae will feed bore into a pod to eat the seed. The larvae then back
out and look for other feeding sites.
