This chapter addresses sod webworms, which refers to a large number of grass-infesting moths and larvae of the family Crambidae (formerly Pyralidae), subfamily Crambinae. Adults are often called lawn moths because of their habitat or snout moths because of the prominent labial palpi that extend in front of the head. Most of the turfgrass-infesting species originally were placed in the genus Crambus, which is distributed practically worldwide. About 100 species are recognized in North America. The six most important sod webworm species in the eastern temperate regions of the United States include the bluegrass webworm; the striped sod webworm; the silver-striped webworm; the larger sod webworm; the corn root webworm; and the subterranean webworm, also known as the cranberry girdler. Sod webworms restrict their feeding, with rare exceptions, to plants of the family Gramineae, and turfgrasses serve as ideal host plants. The chapter then considers tropical-region sod webworms.
