© National Geographic Society 256 Beetles Do Good and Evil. Japanese Invaders at Lower Right Are Plant-eating Pests; Ladybirds and Scavengers, Beneficial Ladybirds (above, left and right) used to be raised for sale to attack crop pests. An Australian species saved California's orange groves from the cottony-cushion scale. The "stranger" marked with a U (on a Shasta daisy) is a leaf-eating chrysomelid beetle. Scavenger Beetles (lower left) bury dead mice and birds byexcavat ing soil beneath them; then they lay eggs so that the larvae may feed on the carcasses. Because they flee from light,these specimens were kept indarkness until the camera was ready. Larvae of the green and bronze Japanese Beetles, hidden in soil around roots of nursery stock, entered theUnited States undetected in1916.
