About

The pea-leaf weevil is a small beetle that can turn up almost anywhere, including in and around houses. It is the most commonly recorded weevil. As the name suggests, pea-leaf weevils feed on legumes such as peas and beans. Adults feed on the leaves, leaving u-shaped notches at the edges of the leaf. Their larvae live in the soil and feet on the root nodules. They don't usually eat enough to damage plants in gardens and allotments.

Pea-leef weevils spend the winter as adults, tucked away in grass or similar hiding spots. They become active early in spring, with females laying eggs throughout spring and early summer. When the larvae are fully grown, they pupate in the soil and emerge as adults a few weeks later.

How to identify

The pea-leaf weevil has a short, blunt 'snout' (officially called a rostrum) and protruding, rounded eyes. The wing cases covering its back are fairly narrow and straight-sided. They have neat, alternating pale and dark stripes running the length of them. There are several similar species, though this is the one most likely to be encountered.

Distribution

Common and widespread in England and Wales, with scattered records in Scotland, Northern Ireland and Isle of Man.

Did you know?

Female pea-leaf weevils can lay up to 40 eggs a day, placing them on the ground around their foodplant, or on nearby leaves.
