Sod webworm damage is most noticeable during which times of day?

• A. Midday
• B. Evening or early morning
• C. Night
• D. Dawn only

Answer: (B)

Nocturnal feeding by sod webworm larvae means the damage shows up when the grass has just finished being fed for the night. They chew blades at night and hide in thatch or soil by day, so the most noticeable time to see the impact is during the evening after feeding and again in the early morning before heat and sun force the larvae back underground. Midday feeding doesn’t occur, so damage is less obvious then, and dawn is a common time to notice patches, but the best window to observe it is evening or early morning when recent feeding is evident.
