Tropical Sod Webworm Identification in South Florida
Tropical sod webworms are destructive lawn caterpillars commonly found throughout South Florida, especially in residential lawns, golf courses, sports fields, parks, and landscaped turfgrass environments. These pests feed on grass blades and may create widespread brown patches and thinning turf in warm-season lawns. Adult tropical sod webworms are small tan moths, while larvae are caterpillars that actively feed at night on turfgrass. The scientific name for the tropical sod webworm is Herpetogramma phaeopteralis, and they are also commonly referred to as lawn webworms or sod worms.
