![]() ![]() Tenebrionidae (darkling beetles) live in various habitats as scavengers or predators. The lucanids feed in logs and stumps as larvae the adults often feed on juices from damaged trees, particularly at openings of larval tunnels of Cerambycidae (long-horned beetles). Moderate numbers of larvae and adults of Passalidae ( bess beetles), which feed on rotting logs, generally are found together apparently the adults protect and feed their young, an unusual habit among beetles. Some of the small buprestids are leaf miners that is, they feed on leaf cells between the upper and lower surfaces of a leaf. Buprestidae bore into living and dead trees, generally feeding on the cambium layer. The Dynastinae (rhinoceros, Hercules, and elephant beetles) feed in rotting wood, decaying vegetation, or humus. The adults of Cetoniinae feed on pollen and tree juices the larvae, often called white grubs, feed on organic matter in the soil and may damage plant roots. The larvae of Rutelinae ( shining leaf chafers), which have similar habits, sometimes feed in humus or in rotten wood. The Melolonthinae (June beetles, chafers) are phytophagous, the larvae usually feeding on roots of grasses or other plants and the adults feeding on leaves. Eggs are laid on the buried balls, and the larvae feed on the excrement. Some make balls of animal excrement (e.g., of cattle) and roll them to protected spots for burying. Clerid larvae are largely predators of wood-boring beetle larvae, although some of the adults are flower feeders.Īmong the lamellicorns, the true scarabs ( Scarabaeinae) and several related groups (e.g., Aphodiinae, Geotrupinae) are dung feeders. The lampyrids (fireflies), which are often luminous both as larvae and as adults, are primarily predators upon snails. Most larvae of Cantharidae (soldier beetles), which prey on worms and larvae of other insects, occur under bark, in rotting wood, or in soil the adults are usually found on flowers. Some Elateridae (click beetles) are predatory as larvae, feeding on the larvae of wood-boring insects others feed on roots of various crops. Heterocerids and histerids prey on fly larvae or those of beetles living in excrement or in carrion. Ptinidae ( spider beetles) feed on dead insects and animal skins, as do certain Anobiidae (e.g., the cigarette beetle, which also feeds on tobacco and other dried products). Dermestids feed on dead animal skins, dead insects, birds’ nests, other animal nests, and accumulations of debris. Silphids, which dig under small dead animals so that they settle into the ground, lay their eggs on the carrion, on which the larvae feed. Hydrophilids are water scavenger beetles and eat various dead organisms and live algae in fresh water. Staphylinids (rove beetles) are usually predatory, both as larvae and as adults. Gyrinids ( whirligig beetles) feed both on water insects and on other insects that fall into the water. Both larval and adult dytiscids (diving beetles) feed on various water insects, small frogs, and small fish. The predatory larvae remain more hidden than the adults. ![]() Many small carabids live in moss on tree trunks and feed on small insects hidden in the moss.
