Worm - Sod Webworm

Sod Webworm

There are several species of caterpillars called sod webworms that can be highly destructive pests of Ohio lawns. They may also become important pests of grass covered parks, cemeteries, golf courses. They have even been noted to cause damage in small grain crops such as corn, wheat and oats. Damage to grass is caused by the feeding of the larval or "worm" stage. The adult moth does not cause damage to turf, other plants or clothing.
