Which insect is an example of a stem and leaf feeding pest of Iowa turfgrass?

The sod webworm is an example of a stem and leaf feeding pest of Iowa turfgrass because it primarily damages grass by feeding on the blades and stems. These larvae create irregular holes in the leaves and can severely weaken the plant, leading to brown patches and an overall decline in turf health. The feeding habits of sod webworms make them particularly problematic during warm weather when their populations can increase rapidly.

In the context of turf management, understanding the specific feeding behavior of pests like the sod webworm is crucial, as it informs control strategies and timing for interventions. Effective management often includes monitoring for signs of damage and applying appropriate pest control measures when necessary to protect turfgrass health.
