Amarygmus is a genus of darkling beetles (family Tenebrionidae). It is in the tribe Amarygmini and is the oldest genus of the tribe. [1] The genus occurs in Australia (mainly in the north), New Guinea, Hawaii, [2] Africa and Eurasia. [3]
Amarygmus is a variable genus. Some descriptions of adults are given below:
Larvae and pupae of A. morio have been described:
Larvae of some species feed on lichens at night. [3]
Larvae of A. morio have been collected from the trunk of a decayed mango tree. [2]
Amarygmus tristis is associated with old woody plants, including Acacia mearnsii , Eucalyptus spp., Solanum mauritianum and Virgilia capensis . During the day, it occurs in holes or under bark. It is rather common in gardens. [4]
Beetles are insects that form the 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 insects 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. 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 eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops.
The devil's coach-horse beetle is a species of beetle belonging to the large family of the rove beetles (Staphylinidae). It was originally included in the genus Staphylinus in 1764, and some authors and biologists still use this classification.
The Lymexylidae, also known as ship-timber beetles, are a family of wood-boring beetles. Lymexylidae belong to the suborder Polyphaga and are the sole member of the superfamily Lymexyloidea.
The Chrysomelinae are a subfamily of leaf beetles (Chrysomelidae), commonly known as broad-bodied leaf beetles or broad-shouldered leaf beetles. It includes some 3,000 species around the world.
Tenebrioninae is the largest subfamily of the darkling beetles (Tenebrionidae), containing flour beetles, among others. Tenebrioninae contains more than 20 tribes.
Chalcopteroides is a genus of darkling beetle, defined by Embrik Strand in 1935, and replacing the older name Chalcopterus which was preoccupied. The type species is Chalcopterus iridicolor. The genus occurs throughout Australia.
Callipogon relictus is a species of longhorn beetle which is mostly found in Korea, but also in China and southern part of Russian Far East. It inhabits mixed and deciduous forests. The population of Callipogon relictus is decreasing due to deforestation and uncontrolled collection, and therefore the species are listed in the Russian Red Book.
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.
Brachypsectra fulva is a species of beetle in the Brachypsectridae family commonly known as the Texas beetle.
Heteronychus arator is a species of beetle in the subfamily Dynastinae. It is commonly called African black beetle or black lawn beetle. It is native to Africa and it is an introduced species in Australia, Norfolk Island and the North Island of New Zealand.
Tillus elongatus is a species of beetle in the family of checkered beetles Cleridae. It is found in the Palearctic. The “Holz” in the German common name Holzbuntkäfer indicates that these checkered beetles are found in wood. Although Tillus elongatus can reach up to a size of 1 cm long, the beetle is rarely seen by humans, as it primarily resides hidden in the wood of trees. The colouration of the males differs from that of the females.
Bucolus fourneti is a native Australian, small, hairy coccinellid beetle approximately 2.1-4.5 mm in diameter. It was described by Étienne Mulsant in 1850
Larinus turbinatus is a species of true weevil in the family of beetles known as Curculionidae.
Lagriinae is a subfamily of long-jointed beetles in the family Tenebrionidae. There are more than 270 genera in Lagriinae, grouped into 11 tribes.
Harmonia octomaculata is a species of ladybird of the family Coccinellidae. It is found throughout India, Pakistan, Nepal, Bangladesh, Sri Lanka, Micronesia, and Australia.
Lamprolina is an Australian genus of leaf beetles (Chrysomelidae) found in Victoria, New South Wales, and Queensland.
Amarygmini is a tribe of darkling beetles in the family Tenebrionidae. There are more than 80 genera in Amarygmini.
Meracantha contracta is a species of darkling beetle found in North America.
Rhantus suturalis, commonly known as the supertramp beetle or cosmopolitan diving beetle, is a species of diving beetle (Dytiscidae) with a cosmopolitan distribution.
Perothops is a genus of false click beetles in the family Eucnemidae containing 3 species. They are known as beech-tree beetles or perothopid beetles. They are small as they are only 10–18 millimeters long. It is the only genus in the monotypic subfamily Perothopinae. They are small, dark-colored beetles that are found across the United States, generally in forests. The genus was discovered by Johann Friedrich von Eschscholtz in 1836. It used to be considered a family not part of Eucnemidae. The genus's name is from Greek, translating to "maimed/crippled eye" or "eye of little necklaces/bands", referring to the placement of perothopid eyes.
