context_page_description: The genus Crambus includes around 155 species of moths in the family Crambidae, distributed globally. The adult stages are called crambid snout moths, while the larvae of Crambus and the related genus Herpetogramma are the sod webworms, which can damage grasses.
context_section_description: Sod webworms have a bivoltine life cycle with four stages: egg, larva, pupa and imago (adult). They overwinter as larvae in their final or penultimate instar in the thatch or soil. With the coming of warmer weather, the larvae will pupate, and moths will appear in late spring or early summer. The first generation of eggs is laid in June, with larvae appearing in June and lasting until July. Adult moths appear from July until August. Under favorable conditions, a second generation will occur, with the adult stage laying eggs in early October.
