What is a typical characteristic of sod webworm caterpillars?

Sod webworm caterpillars are typically characterized by a length of around 1 inch or less, which aligns with the correct answer. This particular measurement is important because it helps in identifying them among other caterpillars and pests that may be present in turfgrass. Recognizing the size aids pest management strategies, as it dictates the appropriate control measures and timing for intervention.

The other descriptions do not accurately represent sod webworms. While some caterpillars can be more colorful or larger, sod webworms are generally not bright red or striped, nor are they known to grow to several inches long. Understanding these characteristics allows for better identification of the pest and effective management within turfgrass environments.
