Adephaga
The Adephaga (from Greek ἀδηφάγος, ''adephagos'', "gluttonous") are a suborder of beetles, and with more than 40,000 recorded species in 10 families, the second-largest of the four beetle suborders. Members of this suborder are collectively known as adephagans. The largest family is Carabidae (ground beetles) which comprises most of the suborder with over 40,000 species. Adephaga also includes a variety of aquatic beetles, such as predaceous diving beetles and whirligig beetles. Anatomy Adephagans have simple antennae with no pectination or clubs. The galeae of the maxillae usually consist of two segments. Adult adephagans have visible notopleural sutures. The first visible abdominal sternum is completely separated by the hind coxae, which is one of the most easily recognizable traits of adephagans. Five segments are on each foot. Wings The transverse fold of the hind wing is near the wing tip. The median nervure ends at this fold, where it is joined by a cro ...

Beetles
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aspidytidae
Aspidytidae is a family of aquatic beetles of the suborder Adephaga, described in 2002 from specimens in South Africa and China. There are only two known species in the family and these were originally described in the genus ''Aspidytes,''Beutel, R.G., Balke, M. & Ribera, I. (2016) 7.7. Aspidytidae Ribera,Beutel, Balke and Vogler, 2002. In: Beutel, R.G. & Leschen, R.A.B. (eds.): ''"Handbook of Zoology, Arthropoda: Insecta. Coleoptera, Beetles. Vol. 1: Morphology and Systematics"'' (Archostemata, Adephaga, Myxophaga, Polyphaga partim). 2nd Edition. Walter de Gruyter, Berlin. pp. 141-149. but later the new genus ''Sinaspidytes'' was erected for the species found in China''.'' The family can also be referred to by its trivial name cliff water beetles. Description Cliff water beetles have a streamlined body that is dorsally convex. Their size ranges from 4.8 - 7.0 mm in length. Dorsal side is predominantly black and cuticle is shiny. The head is laterally rounded and shortened wit ...

Coptoclavidae
Coptoclavidae is an extinct family of aquatic beetles in the suborder Adephaga. The Coptoclavidae lived from the Late Triassic to the Early Cretaceous. Coptoclavidae is a member of the adephagan clade Dytiscoidea, which contains other aquatic beetles. Suggested reasons for their extinction to include the rise of teleost fish, or competition with Gyrinidae and Dytiscidae, which possess defensive secretions and sucking channels in the mandibles of larvae, which coptoclavids likely lacked. It has been suggested that the genus '' Timarchopsis'' and the subfamily Timarchopsinae are only distantly related to other coptoclavids based on cladistic analysis, with ''Timarchopsis'' being more closely related to geadephagans like carabids and trachypachids instead. Another study also suggested similarly for '' Coptoclavisca'' and possibly other ''c''optoclaviscines.

Whirligig Beetle
The whirligig beetles are water beetles, comprising the family Gyrinidae that usually swim on the surface of the water if undisturbed, though they swim underwater when threatened. They get their common name from their habit of swimming rapidly in circles when alarmed, and are also notable for their divided eyes which are believed to enable them to see both above and below water. The family includes some 700 extant species worldwide, in 15 genera, plus a few fossil species. Most species are very similar in general appearance, though they vary in size from perhaps 3 mm to 18 mm in length. They tend to be flattened and rounded in cross section, in plain view as seen from above, and in longitudinal section. In fact their shape is a good first approximation to an ellipsoid, with legs and other appendages fitting closely into a streamlined surface. Whirligig beetles belong to the beetle suborder Adephaga, which also includes ground beetles and diving beetles. Description Wh ...

Haliplidae
The Haliplidae are a family of water beetles that swim using an alternating motion of the legs. They are therefore clumsy in water (compared e.g. with the Dytiscidae or Hydrophilidae), and prefer to get around by crawling. The family consists of about 200 species in 5 genera, distributed wherever there is freshwater habitat; it is the only extant member of superfamily Haliploidea. They are also known as crawling water beetles or haliplids. Description The imagines of these beetles are generally oval in shape, with a very convex upperside, and are generally long. They are generally yellowish to light brown in color, frequently with light and dark patterns dotted with 10 or more rows of punctures on the elytra. The family's most distinctive characteristic is the large coxal plates of the hindlegs, which are immobile (though not fused in the centerline) and extend back along the underside to cover most of the abdomen base and the hindleg trochanters and femora. They are used as ai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trachypachidae
The Trachypachidae (sometimes known as false ground beetles) are a family of beetles that generally resemble small ground beetles, but that are distinguished by the large coxae of their rearmost legs. There are only six known extant species in the family, with four species of ''Trachypachus'' found in northern Eurasia and northern North America, and two species of ''Systolosoma'' in Chile and Argentina. They were much more diverse in the past, with dozens of described species from the Mesozoic. Their habits are similar to those of the ground beetles; they are usually found in the leaf litter of conifer forests, and are thought to be mostly predators and scavengers, active during the day ( diurnal). According to entomologist George Ball, "the most interesting thing about this small family is its uncertain phylogenetic relationships"; it has previously been classified as a subfamily of Carabidae, and as a family been placed in several different positions relative to other beetle ...

Hygrobiidae
''Hygrobia'' is a genus of aquatic beetles native to Europe, North Africa, China and Australia. It is the only genus in the family Hygrobiidae, also known as the Paelobiidae.Nilsson, A. N. (2006)Which name is valid – Hygrobiidae or Paelobiidae?''Latissimus'' 21 37–39. These are known commonly as squeak beetles or screech-beetles. There are six known living species, with a highly disjunct distribution, and one extinct species, ''Hygrobia cretzschmari''. Biology All species occur in lowland areas Dettner, K. (2005). Noteridae. ''Handbook of Zoology'', ''4'', 72–90. and are mainly found in stagnant water.Holmen, M. (1987). Family Hygrobiidae. ''The aquatic Adephaga (Coleoptera) of Fennoscandia and Denmark''. Brill, 136–142.

Ground Beetle
Ground beetles are a large, cosmopolitan distribution, cosmopolitan family (biology), family of beetles, the Carabidae, with more than 40,000 species worldwide, around 2,000 of which are found in North America and 2,700 in Europe. As of 2015, it is one of the 10 most species-rich animal families. They belong to the Adephaga. Members of the family are primarily carnivorous, but some members are phytophagous or omnivorous. Description and ecology Although their body shapes and coloring vary somewhat, most are shiny black or metallic and have ridged wing covers (elytra). The elytra are fused in some species, particularly the large Carabinae, rendering the beetles unable to fly. The species ''Mormolyce phyllodes'' is known as violin beetle due to their peculiarly shaped elytra. All carabids except the quite primitive flanged bombardier beetles (Paussinae) have a groove on their arthropod leg, fore leg tibiae bearing a comb of hairs used for cleaning their antenna (biology), antennae. ...
