Histeridae is a family of beetles commonly known as clown beetles or hister beetles. This very diverse group of beetles contains 3,900 species found worldwide. They can be easily identified by their shortened elytra that leaves two of the seven tergites exposed, and their geniculate (elbowed) antennae with clubbed ends. These predatory feeders are most active at night and will fake death if they feel threatened. This family of beetles will occupy almost any kind of niche throughout the world. Hister beetles have proved useful during forensic investigations to help in time of death estimation. Also, certain species are used in the control of livestock pests that infest dung and to control houseflies. Because they are predacious and will even eat other hister beetles, they must be isolated when collected.
The Cucujidae, or flat bark beetles, are a family of distinctively flat beetles found worldwide under the bark of dead trees. The family has received considerable taxonomic attention in recent years and now consists of 70 species distributed in five genera. It was indicated Cucujus species are scavengers, only feeding on pupae and larvae of other insects and on other subcortical beetles such as their own. Since the Cucujidae prey on larvae of potentially tree damaging beetles that spread fungal diseases, they are considered to be beneficial to the health of living trees.
The emerald ash borer, also known by the acronym EAB, is a green buprestid or jewel beetle native to north-eastern Asia that feeds on ash species. Females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years. In its native range, it is typically found at low densities and does not cause significant damage to trees native to the area. Outside its native range, it is an invasive species and is highly destructive to ash trees native to Europe and North America. Before it was found in North America, very little was known about emerald ash borer in its native range; this has resulted in much of the research on its biology being focused in North America. Local governments in North America are attempting to control it by monitoring its spread, diversifying tree species, and through the use of insecticides and biological control.
A bark beetle is the common name for the subfamily of beetles Scolytinae. Previously, this was considered a distinct family (Scolytidae), but is now understood to be a specialized clade of the "true weevil" family (Curculionidae). Although the term "bark beetle" refers to the fact that many species feed in the inner bark (phloem) layer of trees, the subfamily also has many species with other lifestyles, including some that bore into wood, feed in fruit and seeds, or tunnel into herbaceous plants. Well-known species are members of the type genus Scolytus, namely the European elm bark beetle S. multistriatus and the large elm bark beetle S. scolytus, which like the American elm bark beetle Hylurgopinus rufipes, transmit Dutch elm disease fungi (Ophiostoma). The mountain pine beetle Dendroctonus ponderosae, southern pine beetle Dendroctonus frontalis, and their near relatives are major pests of conifer forests in North America. A similarly aggressive species in Europe is the spruce ips Ips typographus. A tiny bark beetle, the coffee berry borer, Hypothenemus hampei is a major pest on coffee plantations around the world.
Fire-coloured beetles is the common name for members of the tenebrionoid family Pyrochroidae. The family is found worldwide, and is most diverse at temperate latitudes. Adults measure 2–20 millimetres (0.079–0.787 in); larvae reach 35 millimetres (1.4 in). Larvae of Pyrochroinae are found associated with the bark of dead trees. They are probably mostly fungivorous, although they may become cannibalistic if too crowded.
The family Pythidae is a small group of tenebrionoid beetles with no vernacular common name, though recent authors have coined the name dead log bark beetles. There are seven genera, which are largely native to the mid-high latitude regions of the Northern Hemisphere and Australia, with one genus also present in the tropical Americas. The larvae are generally found with decaying vegetation and wood on which they feed, while adults are not associated with the larvae and are generally caught using malaise traps and light traps.
The family Scraptiidae is a small group of tenebrionoid beetles sometimes called false flower beetles. There are about 400 species in 30 genera with a world-wide distribution. The adults are found on flowers, sometimes in large numbers, but are also found on foliage. The larvae are typically found under the bark of dead trees. The oldest fossils of the group date to the Eocene.
Cleridae are a family of beetles of the superfamily Cleroidea. They are commonly known as checkered beetles. The family Cleridae has a worldwide distribution, and a variety of habitats and feeding preferences.
Bothrideridae is a family of beetles in the superfamily Coccinelloidea. They are known commonly as the cocoon-forming beetles or dry bark beetles. They occur worldwide with most native to the Old World tropics. In older literature, the family was often included in the family Colydiidae, but is now considered unrelated.
Laemophloeidae, "lined flat bark beetles," is a family in the superfamily Cucujoidea characterized by predominantly dorso-ventrally compressed bodies, head and pronotal discs bordered by ridges or grooves, and inverted male genitalia. Size range of adults is 1–5 mm (0.04–0.2 in) in length. Currently, it contains 40 genera and about 450 species, and is represented on all continents except Antarctica; species richness is greatest in the tropics.
Lamingtonium is the only genus in the family Lamingtoniidae, of the beetle superfamily Cucujoidea. It contains three species endemic to Australia. The holotype of the type species was collected on at Lamington National Park, Binna Burra, Queensland under the bark of a dead tree. The adults and larvae of two species have been found associated with basidiocarps of fungi belonging to the family Polyporaceae.
Phloeostichidae is a family of beetles in the superfamily Cucujoidea. They are typically found under the bark of dead trees. Larvae have been found to consume plant tissue and some fungi, while the adults appear to be exclusively fungivores. The family contains four extant genera, Phloeostichus is native to the Palearctic, Rhopalobrachium is native to central-southern South America and eastern Australia, Hymaea is native to southeastern Australia, and Bunyastichus is found in Tasmania.
Glischrochilus[note 1] is a genus of sap-feeding and predatory beetles under the family Nitidulidae, subfamily Cryptarchinae. Most members of this genus are commonly known as picnic beetles or beer bugs.
The Brachypsectridae are a family of beetles commonly known as the Texas beetles. There are only two extant genera, Brachypsectra and Asiopsectra. Brachypsectra has a cosmopolitan distribution, mostly in arid regions, while Asiopsectra is found in Central Asia and the Middle East.
Anoplophora is a genus of beetles in the longhorn beetle family (Cerambycidae). They are native to Asia. Most are large and colorful and thus are depicted in artwork and sought after by beetle collectors. The genus also includes several notorious pest insects.
Ips is a genus of beetles in the family Curculionidae, the true weevils. They are bark beetles, members of the subfamily Scolytinae. Species are distributed throughout the Northern Hemisphere. Some are known as introduced species in Australia and Africa. Many species are pests of forest trees, especially pines and spruces. They are known commonly as engraver beetles, ips engraver beetles, and pine engravers.
Boros is a genus of conifer bark beetles in the family Boridae. There are at least two described species in Boros.
Deretaphrus is a genus of dry bark beetles in the family Bothrideridae. A taxonomic revision of the genus published in 2013 listed 25 species, which exhibit a disjunct distribution. There are 22 species of the genus described from Australia, with single species also being found in each of New Caledonia, Bolivia, and North America.
Myrabolia is the only genus in the beetle family Myraboliidae in the superfamily Cucujoidea. It has about 13 species, found in Australia. Adults and possibly larvae live under the bark of Eucalyptus trees.
Boros schneideri is a species of beetle belonging to the family Boridae.
