Curculionidae - (true weevils)

This is a very large familiy with more than 60,000 plant-feeding species, including many pests of crops and stored products. Most of the damage is done by the larvae which bore into plant tissue.

Most species of Curculionidae can be easily recognized by the long snout and the elbow-shaped antennae which arise from the middle of the snout. With the mouthparts at the tip of the snout, the weevils can create deep holes in plant tissue, usually for depositing eggs. The size of most species ranges from 2 to 20 mm, but some are larger (e.g. the red palm weevil). The body has typically an oval shape and is often covered with scales. The antennae have a 3-segmented club. The larvae are leg-less.

Among the more important pest species are the:
