Araecerus fasciculatus can reach a length of about 3–5 millimetres (0.12–0.20 in). These small weevils are dome shaped, with dark brown mottled elytra and hairy body. Antennae in males are longer than the body, with the three last segments forming a club. The last segment of the abdomen is not covered by the elytra.
They are a worldwide pest of cocoa, coffee and many of other plants. They commonly attack stored commodities. The larvae dig tunnels into the seeds, pupate inside them and adults emerge boring a hole.
