CHAFER

any of several beetles of the insect subfamily Melolonthinae (family Scarabaeidae, order Coleoptera). The leaf chafers (Macrodactylus) eat foliage; the grub feeds underground on plant roots. The adult female deposits her eggs in the soil, and the larvae live underground for several years. They pupate in the fall, but the adults remain underground until the following spring. A well-known, destructive chafer is the rose chafer (M. subspinosus), a tan, long-legged beetle that feeds on the flowers and foliage of grapes, roses, and other plants. Poultry that eat rose chafer grubs may be poisoned. Other scarab subfamilies are also called chafers; see also flower chafer; shining leaf chafer.
