Acromis
''Acromis'' is a genus of beetles belonging to the family Chrysomelidae The beetle family Chrysomelidae, commonly known as leaf beetles, includes over 37,000 (and probably at least 50,000) species in more than 2,500 genera, making it one of the largest and most commonly encountered of all beetle families. Numerous s .... The three known species of this genus are found in Southern America. These species exhibit subsocial behavior, where the females lay clusters of eggs that she guards until they hatch, the larvae mature, pupate, and young adults disperse.Chaboo, C.S. 2001.

Acromis Spinifex
''Acromis spinifex'' is a species of tortoise beetle from South America. The males have enlarged elytra which are probably used in male–male combat, while females are among the few tortoise beetles to show maternal care of their offspring. Distribution ''Acromis spinifex'' is found across South America, from Trinidad and Tobago and Venezuela in the north to Peru, northern Argentina and Paraguay in the south. Description As with other species in the genus ''Acromis'', ''A. spinifex'' shows conspicuous sexual dimorphism. The elytra of males extend sideways and forwards to form flattened plates. Other species in the genus have been studied more closely, and they have been observed to engage in male–male combat, in which the flattened parts of the elytra are often pierced; such holes are frequently found in museum specimens of ''Acromis''. Males are long and wide, while females are slightly smaller, long and wide. Ecology and life cycle The host plants of ''Acromis spinif ...

''Acromis'' is a genus of beetles belonging to the family Chrysomelidae. The three known species of this genus are found in Southern America.

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 ...

Cassidinae
The Cassidinae (tortoise and leaf-mining beetles) are a subfamily of the leaf beetles, or Chrysomelidae. The antennae arise close to each other and some members have the pronotal and elytral edges extended to the side and covering the legs so as to give them the common name of tortoise beetles. Some members, such as in the tribe Hispini, are notable for the spiny outgrowths to the pronotum and elytra. Description The "cassidoids" have a rounded outline with the edges of the pronotum and elytra expanded, spreading out to cover the legs and head. They are often colourful and metallic, with ornate sculpturing; a few species have the ability to change colour due to water movements within the translucent cuticle. All members of the subfamily have the mouthparts reduced into a cavity in the head capsule, the legs have four segmented tarsi. The hispoids have larvae that are ecological diverse as leaf miners or cryptic exophagous feeders, while the cassidoids feed freely externally ...

Louis Alexandre Auguste Chevrolat
Louis Alexandre Auguste Chevrolat (29 March 1799, Paris – 16 December 1884, Paris) was a French entomologist. He specialized mainly on the beetles and was a founder of the Societe entomologique de France in 1832. Chevrolat worked as a toll administrator in government service in Paris. He was an amateur entomologist who studied mainly beetles and birds. He published nearly 250 notes and papers and was the Species description, author of more than 2,000 species. He was one of the founders of the Société entomologique de France in 1832. On his death, his collection was dispersed. Part of his collection is now in the Natural History Museum in London along with some manuscripts. Works (Selection) * 1833a. Description de Buprestis analis. ''Magasin de Zoologie'' 1833.

Pierre François Marie Auguste Dejean
Pierre François Marie Auguste Dejean (; 10 August 1780 – 17 March 1845), was a French soldier and entomologist. Dejean described a large number of beetles in a series of catalogues. A soldier of fortune during the Napoleonic Wars, he rose to the rank of lieutenant general and ''aide de campe'' to Napoleon. He amassed vast collections of Coleoptera, some even collected on the battlefield at Battle of Waterloo, Waterloo. At the Battle of Alcañiz, battle of Alcanizas he took time out of battle to pick up a beetle that he pinned on to cork on the inside of his helmet. After victory, he was pleased to find the beetle intact. He listed 22,399 species in his cabinets in 1837—at the time, the greatest collection of Coleoptera in the world. In 1802, he began publishing a catalogue of his vast collection, including 22,000 species names. Dejean was an opponent of the Principle of Priority in International Code of Zoological Nomenclature, nomenclature. "''I have made it a rule alway ...

Carolus Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chrysomelidae
The beetle family Chrysomelidae, commonly known as leaf beetles, includes over 37,000 (and probably at least 50,000) species in more than 2,500 genera, making it 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 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. Members of former chrysomelid subfamilies ( Orsodacnidae and Megalopodidae) are also difficult to differentiate from true chrysomelids. Adult and larval leaf beetles feed o ...
