Strawberry root weevil
The adult strawberry root weevil is about six millimeters long, and is dark brown/black in color. They are often found in the leaves and foliage of the plants they feed on. The adult weevil's elytra are fused together, which means they are unable to fly. The larvae can be up to thirteen millimeters long when fully grown and they are found near the roots of the plants they are infesting. The larvae are white, legless, with a darker colored head and are often C-shaped.
The weevil overwinters as a larva deep in the soil, or as an adult under stones or other sheltered places. Larvae feed on roots and weaken or kill small trees. They are whitish, C-shaped, and about 8 mm long when full grown, much smaller than white grubs. They pupate in the upper layers of soil in the spring and change into adults later in the spring or in summer, joining the adults of the previous summer to feed on leaves and fruit.
The adults lack functional wings and do not fly. There are no males, and reproduction is asexual. Eggs are laid at random in the soil in summer around food plants, and, on hatching, the larvae feed on the roots until late fall, when they hibernate.
