Elateriformia
Elateriformia is an infraorder of polyphagan beetles. The two largest families in this group are buprestids, of which there are around 15,000 described species, and click beetles, of which there are around 10,000 described species. The infraorder consists of six superfamilies:Lawrence, J. F. & Newton, A. F. Jr. 1995.

Byrrhoidea
Byrrhoidea is a superfamily of beetles belonging to Elateriformia that includes several families which are either aquatic or associated with a semi-aquatic habitat. Other than the superfamily Hydrophiloidea, most of the remaining Polyphagan beetles which are aquatic are in this superfamily. Description Adults of many Byrrhoidea have exocone eyes (with expanded corneal lens). The anterior edge of the scutellar shield is often abruptly elevated (except in Psephenidae and Cneoglossidae). A variety of byrrhoids have the first three abdominal ventrites solidly fused together. Larvae of most Limnichidae have one pair of anal hooks on the tenth abdominal segment, while Cneoglossidae and Ptilodactylidae have three or more hooks on each side of this segment. Larvae of Lutrochidae and Elmidae, as well as the limnichid genus ''Hyphalus'', have anal gill tufts. Almost all byrrhoid larvae have anterior abdominal spiracles that are biforous (or bilabiate) in shape. The degree of wing ...

Elateroidea
The Elateroidea are a large superfamily of beetles. It contains the familiar click beetles, fireflies, and soldier beetles and their relatives. It consists of about 25,000 species. Description Elateroidea is a morphologically diverse group, including hard-bodied beetles with 5 abdominal ventrites, soft-bodied beetles with 7-8 ventrites connected with membranes (formerly known as cantharoids), and beetles with intermediate forms. They have a range of sizes and colours, but in terms of shape, they are usually narrow and parallel-sided as adults. Many of the sclerotised elateroids ( Cerophytidae, Eucnemidae, Throscidae, Elateridae) have a clicking mechanism. This is a peg on the prothorax which fits into a cavity in the mesothorax. When a click beetle bends its body, the peg snaps into the cavity, causing the beetle's body to straighten so suddenly that it jumps into the air. Most beetles capable of bioluminescence are in the Elateroidea, in the families Lampyridae (~2000 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyphaga
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 discovered thus far. 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 beetle Elateridae or clic ...

Beetle
Beetles are insects that form the Taxonomic rank, order Coleoptera (), in the superorder Holometabola. 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 arthropods and 25% of all known animal species; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. However, the number of beetle species is challenged by the number of species in Fly, dipterans (flies) and hymenopterans (wasps). 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 ...

Rhinorhipoidea
''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 that is adapted to digging and which lives primarily (but not solely) underground.

Roy Crowson
Roy Albert Crowson (22 November 1914 in Hadlow, Kent – 13 May 1999) was an English biologist who specialised in the Taxonomy (biology), taxonomy of beetles. He was curator at the Tunbridge Wells Museum, and then lectured at the Zoology Department of the University of Glasgow. The beetle family ''Crowsoniella'' is named in his honour. Life Crowson was born on 22 November in Hadlow, Kent. He was educated at the The Judd School, Judd School, in Tonbridge and then at Imperial College London, Imperial College, London University where he completed his Ph.D. in 1937. Crowson served in the Royal Air Force during the war, and was the Assistant Curator of the Tunbridge Wells Museum from 1938. Crowson moved from the Tunbridge Wells Museum to the Zoology Department of the University of Glasgow from 1949, where he was appointed as a lecturer. He collected beetles and their larvae from around the world and studied the relationships between them. His 1955 monograph, ''The natural classific ...

Heteroceridae
Heteroceridae, the variegated mud-loving beetles, are a widespread and relatively common family of beetles found on every continent except for Antarctica. Around two hundred and fifty species of heterocerids are known to occur worldwide. They are most diverse in tropical and sub-tropical regions. Currently, 87 species are known from the New World, including 34 from the United States. Variegated mud-loving beetles are brownish, dorsoventrally depressed shoreline inhabitants. Superficially they resemble small Scarabaeidae, scarabs with the tibiae armed with rows of robust flattened spines. The beetles live in shallow tunnels that they dig in damp soil around fresh and brackish lakes, rivers and ponds. Heterocerids have been reported to live in intertidal sandflats and on remote oceanic islands. The uniform way in which they live seems to have favored the conservation of a "phenotypical uniformity in external morphology". Consequently, it is often quite difficult to identify one o ...

Scirtoidea
Scirtoidea is a superfamily of beetles. It is traditionally considered to consist of four families: Clambidae, Decliniidae, Eucinetidae and Scirtidae. However, genetic studies have suggested that Clambidae and Eucinetidae belong to a separate superfamily Clamboidea, which also includes Derodontidae. Scirtoidea and Clamboidea are the two earliest diverging lineages of living polyphagans. Two extinct families have also been assigned to this group: *† Mesocinetidae Kirejtshuk and Ponomarenko 2010 Late Jurassic-Early Cretaceous (Asia) *† Elodophthalmidae Kirejtshuk and Azar 2008 monotypic, Lebanese amber, Barremian The Barremian is an age in the geologic timescale (or a chronostratigraphic stage) between 125.77 Ma (million years ago) and 121.4 ± 1.0 Ma (Historically, this stage was placed at 129.4 million to approximately 125 million years ago) It is a ...

Soldier Beetle
The soldier beetles (Cantharidae) are relatively soft-bodied, straight-sided beetles. They are cosmopolitan in distribution. One of the first described species has a color pattern reminiscent of the red coats of early British soldiers, hence the common name. They are also known commonly as leatherwings because of their soft elytra. Historically, these beetles were placed in a superfamily "Cantharoidea", which has been subsumed by the superfamily Elateroidea; the name is still sometimes used as a rankless grouping, including the families Cantharidae, Lampyridae, Lycidae, Omethidae (which includes Telegeusidae), Phengodidae, and Rhagophthalmidae. Soldier beetles often feed on nectar and pollen as well as predating other small insects. The larvae are caterpillar like, dark colored, active and covered in fine hairs, earning them the name velvet worms. They feed on the ground and in foliage hunting eggs, small insects, snails and other small creatures. Evolutionary hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
