The wonderful weevils of Lewis & Clark


Curculionidae, or "true weevils," is a family of Coleoptera (beetles). It is the largest family of animals in the world, with over 60,000 described species. Of the weevil species in Pacific Northwest forests, many live on conifer trees. The mature adults feed on the twigs and foliage while the larvae live in the soil and feed on the roots. Part of their success in diversity is attributed to their characteristic rostrum, a snout-like projection on the head with tiny mouthparts that is used to penetrate and feed on plants as well as to bore holes to lay eggs in. Weevils feed on a wide range of plants, including a variety of crops, stored food products, and trees. As a result, many Curculionidae species cause notable damage in agricultural fields and forests across the U.S. and raise significant pest management issues. This collection contains weevil specimens collected on Lewis & Clark College campus in Portland, OR.
