Corn armyworms are light tan to grey or dark brown caterpillars which attack many garden crops including corn, grasses and grains.
Damage can be extensive and ruin a crop of corn if left untreated.
Corn armyworms also tend to have either orange, yellow or dark brown contrasting stripes on their bodies. Damage on corn plants may first show up in the form of chewed or frayed looking leaves. This damage usually occurs along the outside edges of the leaves, and eventually entire leaves may be eaten off. Additionally, as the feed through the leaves armyworms will bore into the corn ears themselves causing extensive damage as they feed until there is no more left to eat before moving on to another ear of corn. The tan and grey adult females lay eggs among blades of grass or grains and from them caterpillars hatch.
