The sod webworm is a lawn pest that can infest grass and lawns in Boynton Beach Florida. Among the more important St Augustine grass-infesting species are those belonging to the genus Crambus.
Adult sod webworms, sometimes referred to as "lawn moths" are buff-colored, about 1/2 to 3/4 inches long with snout-like projections extending forward from the head. At rest, they fold their wings around the body, giving them a cylindrical or cigar-shaped appearance. Sod webworm larvae (caterpillars) are gray to tan with small dark spots on the body and brown heads. They reach 3/4 to 1 inch when fully grown.
Sod webworms overwinter as partially grown larvae in silk lined tunnels in the thatch and soil. In most years in Boynton Beach Florida, larval activity resumes in April or early May. Sod Webworms complete development, pupate and emerge as adults from mid-May to mid-June. Adult sod webworms rest in the grass and on shrubbery during the day and randomly scatter their eggs into the grass in the late afternoon and early evening while flying in a zigzag fashion just above the lawns surface. Eggs hatch in about one week, and first-generation larvae feed until mid-summer. A second and partial third generation occurs during the remainder of the season. Frequently, generations overlap with all stages present by late summer, this is when O'Hara Pest Control expert lawn care service can help you to keep your lawn looking healthy and patch free.
