Flat bark beetles have a wide range of habits. They are usually found under the bark of freshly cut logs. Most adults and larvae feed on fungi found under bark, but a few species are predaceous on small arthropods. Some species can be major pests of stored products such as cereals, dried fruits and tobacco. The Cucujidae are very flattened and elongated beetles. They are usually reddish, brown or yellow.
