They have four life stages: egg, larva, pupa, and adult. Their eggs are laid in the soil in clusters of up to 20, held together by a slimy clear material. The larva is white with a brown top head and six legs. Mature grubs are about 3/4 inch long. The larva pupates emerging as an adult beetle in about 8-15 days. The adult is a small chestnut-brown in color.
They are known to attack more than 100 plants, feeding on both foliage, buds and open flowers. Adult beetles will start feeding at the margins of leaves. When feeding is heavy, only the midrib of the plant may left. Their favorite plants include butterfly bush, rose, dahlia, aster and chrysanthemum. They can be very destructive, completely destroying both foliage and flowers.
