Polyphaga Families
Polyphaga is the largest and most diverse suborder of beetles. It comprises 144 families in 16 superfamilies, and displays an enormous variety of specialization and adaptation, with over 350,000 described species, or approximately 90% of the beetle species so far discovered. Key characteristics of Polyphaga are that the hind coxa (base of the leg) does not divide the first and second abdominal/ventral plates which are known as sternites. Also, the notopleural suture (found under the pronotal shield) is not present. Etymology The name of ''polyphaga'' is derived from two Greek words: , meaning 'many', and , meaning 'to eat', so the suborder is called the “eaters of many things”. Classification The five main infraorders are: * Bostrichiformia — including furniture beetles and skin beetles * Cucujiformia — includes lady beetles, longhorn beetles, weevils, checkered beetles and leaf beetles * Elateriformia — includes click beetles and fireflies * Scarabaeiformia ...

Cetonia Aurata
''Cetonia aurata'', called the rose chafer or the green rose chafer, is a beetle, long, that has a metallic structurally coloured green and a distinct V-shaped scutellum. The scutellum is the small V-shaped area between the wing cases; it may show several small, irregular, white lines and marks. The underside of the beetle has a coppery colour, and its upper side is sometimes bronze, copper, violet, blue/black, or grey. ''Cetonia aurata'' should not be confused with the North American rose chafer, '' Macrodactylus subspinosus'', or with the rarely seen noble chafer, ''Gnorimus nobilis'', which is very similar to the rose chafer. One way to identify ''Cetonia aurata'' is to look at its scutellum; on the noble chafer the scutellum is an equilateral triangle, but on the rose chafer it is an isosceles triangle. Overview Rose chafers are capable of fast flight; they fly with their wing cases down. They feed on pollen, nectar, and flowers, especially roses. They can be found among ...

Leaf Beetle
The insects of the beetle family Chrysomelidae are commonly known as leaf beetles, and include over 37,000 (and probably at least 50,000) species in more than 2,500 genera, making up one of the largest and most commonly encountered of all beetle families. Numerous subfamilies are recognized, but the precise taxonomy and systematics are likely to change with ongoing research. Leaf beetles are partially recognizable by their tarsal formula, which appears to be 4-4-4, but is actually 5-5-5 as the fourth tarsal segment is very small and hidden by the third. As with many taxa, no single character defines the Chrysomelidae; instead, the family is delineated by a set of characters. Some lineages are only distinguished with difficulty from longhorn beetles (family Cerambycidae), namely by the antennae not arising from frontal tubercles. Adult and larval leaf beetles feed on all sorts of plant tissue, and all species are fully herbivorous. Many are serious pests of cultivated plants, f ...

Rhinorhipus
''Rhinorhipus'' is a genus of beetles that contains a single species, ''Rhinorhipus tamborinensis'' from southern Queensland, Australia. It is the sole member of the family Rhinorhipidae and superfamily Rhinorhipoidea. It is an isolated lineage not closely related to any other living beetle, estimated to have split from other beetles at least 200 million years ago, with studies either considering them the earliest diverging member of Elateriformia, or a basal lineage within Polyphaga. They exhibit feigning death ( thanatosis) when disturbed. Their ecology is poorly known. It is likely that they are fossorial A fossorial () animal is one adapted to digging which lives primarily, but not solely, underground. Some examples are badgers, naked mole-rats, clams, meerkats, and mole salamanders, as well as many beetles, wasps, and bees. Prehistoric evid ... based on their morphology.Lawrence, John F.. "4.1.

Eucinetidae
Eucinetidae is a family of beetles, notable for their large coxal plates that cover much of the first ventrite of the abdomen, sometimes called plate-thigh beetles. The family is small for beetles, with about 50 species in 11 genera, but are found worldwide. Adults are generally elliptical in shape, ranging from 0.8 to 4.0 mm in length, and black or brown in color. The head is small and bent underneath. Eucinetids live in detritus or in fungus-covered tree bark, where both adults and larvae are assumed to eat various sorts of fungi. Around half of the genera possess strongly modified mouthparts, particularly the labrum, adapted for suctorial feeding. Genera These genera belong to the family Eucinetidae: * '' Eucinetella'' * '' Eucinetus'' Germar, 1818 * '' Euscaphurus'' Casey, 1885 * '' Noteucinetus'' Bullians & Leschen, 2005 * ''Nycteus'' Latreille, 1829 * '' Peltocoleops'' Ponomarenko, 1990 * '' Subulistomella'' Sakai, 1980 * †'' Huaxiacinectus'' Hong 1995 Huachi- ...

Derodontidae
Derodontidae is a family of beetles, in its own superfamily, Derodontoidea, sometimes known as the tooth-necked fungus beetles. Beetles of this family are small, between 2 and 6 mm in length, typically with spiny margins on their pronotum (part of the thorax) that give them their name, though the genus ''Laricobius'' lacks these spines. Unusual among beetles, they have two ocelli on the top of their heads. They are related to the Bostrichoidea, which includes the death watch beetles, skin beetles, powder-post beetles and other subgroups. Some species feed on slime molds, but the larvae and adults of the genus ''Laricobius'' are predators of woolly adelgids which attack conifers, and species of this genus are used as biological control agents in the United States for control of balsam woolly adelgid and hemlock woolly adelgid. There are 42 species in 4 genera and 3 subfamilies. The family includes: *Subfamily Derodontinae **Genus ''Derodontus'' (11 species) *Subfamily La ...

Decliniidae
Decliniidae is a family of beetles belonging to Scirtoidea. It contains the single genus ''Declinia'' with two species, ''D. relicta'' and ''D. versicolor'', found in the Russian Far East and Japan, respectively. Little is known of their ecology, and their larvae are unknown. Specimens of ''D. relicta'' were found with pollen grains in their gut.Lawrence, John F..

Scirtidae
Scirtidae is a family of beetles ( Coleoptera). These beetles are commonly referred to as marsh beetles, as the larvae are typically associated with stagnant water, but can be found in flowing water. Adults prefer decomposing plant material near the water's edge. More than an estimated 600 species are known worldwide, distributed among at least 60 genera. Genera These 81 genera belong to the family Scirtidae: * '' Accolabass'' Watts, 2009 * '' Alpestriscyphon'' Watts, Cooper & Libonatti, 2020 * '' Amplectopus'' Sharp, 1886 * '' Anocyphon'' Watts, Cooper & Libonatti, 2020 * '' Anthocara'' Watts, Cooper & Libonatti, 2020 * '' Anticyphon'' Ruta, 2016 * '' Atopida'' White, 1846 * '' Austrocyphon'' Zwick, 2013 * '' Brachelodes'' Yablokov-Khnzorian, 1961 * '' Brachycyphon'' Fairmaire, 1896 * '' Byrrhopsis'' Champion, 1913 * '' Calvariopsis'' Ruta, 2019 * ''Calvarium'' Pic, 1918 * '' Chameloscyphon'' Watts, 2011 * '' Chilarboreus'' Ruta, 2011 * '' Contacyphon'' Des Gozis, 1886 * '' ...

Hydrophilidae
Hydrophilidae, also known colloquially as water scavenger beetles, is a family of beetles. Aquatic hydrophilids are notable for their long maxillary palps, which are longer than their antennae. Several of the former subfamilies of Hydrophilidae have recently been removed and elevated to family rank; Epimetopidae, Georissidae (= Georyssinae), Helophoridae, Hydrochidae, and Spercheidae (= Sphaeridiinae). While the majority of hydrophilids are aquatic, around a third of described species are terrestrial, mostly belonging to the subfamily Sphaeridiinae. With rare exceptions, the larvae are predatory while the adults may be herbivores or predators in addition to scavenging. Many species are able to produce sounds. Species of '' Hydrophilus'' are reported as pests in fish hatcheries. Other species are voracious consumers of mosquito larvae, and have potential as biological control agents. This beetle family contains 2,835 species in 169 genera. Geography Hydrophilid beetles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rove Beetle
The rove beetles are a family (Staphylinidae) of beetles, primarily distinguished by their short elytra (wing covers) that typically leave more than half of their abdominal segments exposed. With roughly 63,000 species in thousands of genera, the group is currently recognized as the largest extant family of organisms. It is an ancient group, with fossilized rove beetles known from the Triassic, 200 million years ago, and possibly even earlier if the genus ''Leehermania'' proves to be a member of this family. They are an ecologically and morphologically diverse group of beetles, and commonly encountered in terrestrial ecosystems. One well-known species is the devil's coach-horse beetle. For some other species, see list of British rove beetles. Anatomy As might be expected for such a large family, considerable variation exists among the species. Sizes range from <1 to , with most in the 2–8 mm range, and the form is generally elongated, with some rove beetles being ovoid i ...

Dung Beetles
Dung beetles are beetles that feed on feces. Some species of dung beetles can bury dung 250 times their own mass in one night. Many dung beetles, known as ''rollers'', roll dung into round balls, which are used as a food source or breeding chambers. Others, known as ''tunnelers'', bury the dung wherever they find it. A third group, the ''dwellers'', neither roll nor burrow: they simply live in dung. They are often attracted by the feces collected by burrowing owls. There are dung beetle species of various colors and sizes, and some functional traits such as body mass (or biomass) and leg length can have high levels of variability. All the species belong to the superfamily Scarabaeoidea, most of them to the subfamilies Scarabaeinae and Aphodiinae of the family Scarabaeidae (scarab beetles). As most species of Scarabaeinae feed exclusively on feces, that subfamily is often dubbed ''true dung beetles''. There are dung-feeding beetles which belong to other families, such as the Geo ...

Stag Beetle
Stag beetles are a family of about 1,200 species of beetles in the family Lucanidae, currently classified in four subfamilies.Smith, A.B.T. (2006). A review of the family-group names for the superfamily Scarabaeoidea (Coleoptera) with corrections to nomenclature and a current classification. The Coleopterists Bulletin 60:144–204. Some species grow to over , but most to about . Overview The English name is derived from the large and distinctive mandibles found on the males of most species, which resemble the antlers of stags. A well-known species in much of Europe is ''Lucanus cervus'', referred to in some European countries (including the United Kingdom) as ''the'' stag beetle; it is the largest terrestrial insect in Europe. Pliny the Elder noted that Nigidius called the beetle ''lucanus'' after the Italian region of Lucania where they were used as amulets. The scientific name of ''Lucanus cervus'' adds ''cervus'', deer.
