Chafer

Chafer, a common name for beetles or coleopterous insects, especially for those which, either in the perfect or larval state, are destructive of plants, particularly of the wood, bark, or roots of trees. The word is seldom used alone, but generally as part of a name, with some prefix; thus, we have Cock-chafer, Rose-chafer, Bark-chafer, &c. Käfer is the German word for 'beetle.'
