There are a large number of weevil species. They can be very small (1 mm) to large (60 mm), but are usually between 6-12 mm. Weevils inhabit an enormous variety of habitats and vary in shape and colour. All have a distinct snout with mandibles at the end. The C-shaped larvae are white to cream and grub-like in nature.
Weevils can be pests of both garden plants and commercial crops, or feed on stored products like grain. They drill holes into stems, bulbs or grain, either to feed or to lay their eggs. The larvae will feed on the internal tissue until they pupate.
