Sod webworms start off as caterpillars. They live in the thatch just above the soil. They feed at night on the undersides of leaves. The caterpillars can grow to one inch in length.
Adult moths will begin to emerge late May to early June depending on temperatures. This is when they are most visible. You will see the moths flying in a jerky motion. The adult moth is not the destructive part of this insect’s life. It is the larvae (caterpillar) that is destructive. The problem is that all those little moths are laying eggs. Sometimes a female can drop as much as 200 eggs while flying. It takes 5 to 10 days for the larvae to hatch and start feeding. Damage will appear minimal at first but as the larvae mature the more damage they will be capable of. Sod webworms have two generations a year.
