Quick Summary

The pea weevil (Bruchus pisorum) is a small insect that damages peas by consuming their interiors. Another European variety, Sitona lineatus, feeds on pea leaves. Pea weevils are oval-shaped, typically 5 mm (1/5 inch) long, and dark brown with white markings on their wing covers. Females lay eggs on young pea pods, and the larvae burrow into the peas. Peas infested with pea weevils will float in water. Pea weevils belong to the subfamily Bruchinae, commonly known as seed beetles, which are a type of weevil in the order Coleoptera.123

Coleoptera
Size range and diversity of structure
The Bruchinae (seed beetles, or bean weevils) are short and stumpy, with short stout legs. The head, slightly elongated in front, is similar to that of some curculionid weevils. The Cerambycidae (long-horned beetles), diverse in form and structure, usually have antennae that are longer than the body. Cerambycids may be…
