Pest Biology


Adult vine weevils (8-12 mm) are dull black with patches of tiny yellow bristles. Since they are only active at night, they are seldom seen. Outdoors, adults lay eggs from May to October. The emerging larvae burrow deep into compost and feed on fine roots.

As the larvae grow they attack progressively larger roots, corms, rhizomes, and even strip bark from woody stems. (pictured above right)

The C-shaped larvae (10-14 mm) are white with shiny brown heads, legless, and bristly. Vine weevils over-winter as larvae and pupate in the spring.
