Beetles
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 ...

Colorado Potato Beetle
The Colorado potato beetle (''Leptinotarsa decemlineata''; also known as the Colorado beetle, the ten-striped spearman, the ten-lined potato beetle, and the potato bug) is a beetle known for being a major pest of potato crops. It is about long, with a bright yellow/orange body and five bold brown stripes along the length of each of its wings. Native to the Rocky Mountains, it spread rapidly in potato crops across America and then Europe from 1859 onwards.see pp. 453–454: "Doryphora, Illig.: D. 10-lineata"./ref> The Colorado potato beetle was first observed in 1811 by Thomas Nuttall and was formally described in 1824 by American entomologist Thomas Say. The beetles were collected in the Rocky Mountains, where they were feeding on the buffalo bur, '' Solanum rostratum''. Description Adult beetles typically are in length and in width. They weigh 50–170 mg. The beetles are orange-yellow in color with 10 characteristic black stripes on their front wings or elytra. ...

Myxophaga
Myxophaga is the second-smallest suborder of the Coleoptera after Archostemata, consisting of roughly 65 species of small to minute beetles in four families. The members of this suborder are aquatic and semiaquatic, and feed on algae. Description Myxophaga have several diagnostic features: the antennae are more or less distinctly clubbed with usually fewer than nine segments, mesocoxal cavities are open laterally and bordered by a mesepimeron and metanepisternum, the hind wings are rolled apically in the resting positions. Internally, they are characterised by the presence of six malpighian tubules and the testes are tube-like and coiled. Beetles of this suborder are adapted to feed on algae. Their mouthparts are characteristic in lacking galeae and having a mobile tooth on their left mandible. Taxonomy There are four extant families in the suborder Myxophaga divided between two superfamilies, containing about 65 described species, and at least one extinct family. Superfamil ...

Coccinellidae
Coccinellidae () is a widespread family (biology), family of small beetles. They are commonly known as ladybugs in North America and ladybirds in the United Kingdom; "lady" refers to Mary, mother of Jesus, mother Mary. Entomologists use the names ladybird beetles or lady beetles to avoid confusion with true bugs. The more than 6,000 described species have a global distribution and are found in a variety of habitats. They are oval beetles with a domed back and flat underside. Many of the species have conspicuous aposematic (warning) colours and patterns, such as red with black spots, that warn potential predators that they taste bad. Most coccinellid species are carnivorous predators, preying on insects such as aphids and scale insects. Other species are known to consume non-animal matter, including plants and fungi. They are Promiscuity#Other animals, promiscuous breeders, reproducing in spring and summer in temperate regions and during the wet season in tropical regions. M ...

Rhinoceros Beetle
Dynastinae or rhinoceros beetles are a subfamily of the scarabaeidae, scarab beetle family (biology), family (Scarabaeidae). Other common names – some for particular groups of rhinoceros beetles – include Hercules beetles, unicorn beetles or horn beetles. Over 1,500 species and 225 genera of rhinoceros beetles are known. Many rhinoceros beetles are well known for their unique shapes and large sizes. Some famous species are, for example, the Atlas beetle (''Chalcosoma atlas''), common rhinoceros beetle (''Xylotrupes ulysses''), elephant beetle (''Megasoma elephas''), European rhinoceros beetle (''Oryctes nasicornis''), Hercules beetle (''Dynastes hercules''), Japanese rhinoceros beetle or ''kabutomushi'' (''Allomyrina dichotoma''), ox beetle (''Strategus aloeus'') and the Eastern Hercules beetle (''Dynastes tityus''). Description The Dynastinae are among the largest of beetles, reaching more than in length, but are completely harmless to humans because they cannot ...

Chondropyga Dorsalis
''Chondropyga dorsalis'', the cowboy beetle, is a large beetle endemic to Australia. Description The cowboy beetle grows to 20–25 mm (0.8–1 in) long with females generally slightly larger than males. It has a yellow-brown colouration and when in flight produce a loud buzzing noise which creates the illusion of a large wasp. It also does this when it feels threatened. Distribution and habitat It is found in south eastern Australia - throughout Victoria, New South Wales and part of Queensland. Adults feed on nectar while larvae live in rotten wood. They live in woodlands, dry sclerophyll Sclerophyll is a type of vegetation that is adapted to long periods of dryness and heat. The plants feature hard leaves, short Internode (botany), internodes (the distance between leaves along the stem) and leaf orientation which is parallel or ... forests and residential gardens.

Rove Beetles
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 over 66,000 species in thousands of genera, the group is one of the largest families in the beetle order, and one of the largest families of organisms. It is an ancient group that first appeared during the Middle Jurassic based on definitive records of fossilized rove beetles, with the Late Triassic taxon ''Leehermania'' more likely belonging to Myxophaga. 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 (''Ocypus olens''). 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 for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lamprima Aurata
''Lamprima aurata'', the golden stag beetle, is a species of beetle in the family Lucanidae. In Tasmania, this species is referred to by the common name of Christmas beetle, a name that is normally used for beetles in the family Scarabaeidae, genus '' Anoplognathus''. Description This beetle has an oval, shiny body. It measures between 15 and 25 mm in length. It is fairly variable in coloration, so it has been given many names by various authors.C.A.M. Reid, K. Smith, M. Beatson (2018) Revision of the Genus ''Lamprima'' Latreille, 1804 (Coleoptera: Lucanidae). Zootaxa. 4446(2); 151–202. doi:10.11646/zootaxa.4446.2.1 The colour of the males is typically metallic golden green or yellow with colorful legs, while females may be blue, blue-green or dull brown. Females are smaller than the males, and males have larger mandibles prolonged forwards used for fighting.

Insect
Insects (from Latin ') are Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (Insect morphology#Head, head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes, and a pair of antenna (biology), antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a insect brain, brain and a ventral nerve cord. Most insects reproduce Oviparous, by laying eggs. Insects Respiratory system of insects, breathe air through a system of Spiracle (arthropods), paired openings along their sides, connected to Trachea#Invertebrates, small tubes that take air directly to the tissues.

Protocoleoptera
The Protocoleoptera are a Paraphyly, paraphyletic group of extinct beetles, containing the earliest and most primitive lineages of beetles. They represented the dominant group of beetles during the Permian, but were largely replaced by modern beetle groups during the following Triassic. Protocoleopterans typically possess prognathous (horizontal) heads, distinctive elytra with regular window punctures, Arthropod cuticle, cuticles with tubercles or scales, as well as a primitive pattern of ventral sclerites, similar to the modern Archostemata, archostematan families Ommatidae and Cupedidae. They are thought to have been Xylophagy, xylophagous and Woodboring beetle, wood boring. Nomenclature Protocoleoptera was originally proposed by Robert John Tillyard in 1924 for the extinct genus ''Protocoleus'', assigned to the family Protocoleidae. ''Protocoleus'' is now considered a member of the extinct order Protelytroptera (a stem-group of the modern Dermaptera, the earwigs), which would m ...

Fireflies
The Lampyridae are a family of elateroid beetles with more than 2,000 described species, many of which are light-emitting. They are soft-bodied beetles commonly called fireflies, lightning bugs, or glowworms for their conspicuous production of light, mainly during twilight, to attract mates. The type species is '' Lampyris noctiluca'', the common glow-worm of Europe. Light production in the Lampyridae is thought to have originated as a warning signal that the larvae were distasteful. This ability to create light was then co-opted as a mating signal and, in a further development, adult female fireflies of the genus ''Photuris'' mimic the flash pattern of the '' Photinus'' beetle to trap their males as prey. Fireflies are found in temperate and tropical climates. Many live in marshes or in wet, wooded areas where their larvae have abundant sources of food. Although all known fireflies glow as larvae, only some species produce light in their adult stage, and the location o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
