Sod webworm damage is notably characterized by the appearance of ragged edges on the blades of grass. This occurs because sod webworms, which are larvae of a type of moth, feed on the grass blades at the soil surface. The feeding creates a distinct pattern that results in irregular, jagged edges, making it easily recognizable.

As for the other options, while thin and dry turf can be the result of various stressors including drought, it is not a specific indicator of sod webworm activity. Completely brown turf might suggest a more severe or widespread issue, such as drought or a different pest, rather than the typical pattern presented by sod webworms. Similarly, showing no visible changes does not reflect the feeding behavior typical of these pests, as their presence often results in noticeable damage to the grass blades. Thus, the characteristic of ragged damage is the most accurate representation of sod webworm impact on turf.
