Charidotella Egregia
''Charidotella egregia'' is a species of leaf beetle described by Carl Henrik Boheman Carl Henrik Boheman (10 July 1796 – 2 November 1868) was a Swedish entomologist. Boheman studied at Lund University and trained as an officer, participating in the invasion of Norway in 1814. He had been an enthusiastic entomologist since chil ... in 1855. Along with ''Charidotella sexpunctata'', it is known as a golden tortoise beetle. ''C. egregia'' is able to modify its colour in response to stressful events; normally a golden color, it changes to red with black spots in response to threats, likely a defense against predation.

Carl Henrik Boheman
Carl Henrik Boheman (10 July 1796 – 2 November 1868) was a Swedish entomologist. Boheman studied at Lund University and trained as an officer, participating in the invasion of Norway in 1814. He had been an enthusiastic entomologist since childhood, and was called by the Royal Swedish Academy of Sciences in 1841 to the position of professor and keeper of the Department of Entomology of the Swedish Museum of Natural History in Stockholm. He had been made a member of the Academy in 1838. He retired from the Museum in 1867. Boheman was a specialist in coleoptera, and particularly in Chrysomelidae and Rhynchophora, he collaborated in particular with Carl Johan Schönherr (1772–1848) in his great work on Curculionidae. His other works included ''Årsberättelse om framstegen I insekternas myria ach arachnidernas naturalhistoria under åren 1845 och 1846'' (1847), ''Insecta Caffraria'' (two volumes, 1848–1857), ''Monographia Cassididarum Holmiæ'' (four volumes, 1850–1862) and ...

Leaf Beetle
The insects of the beetle family Chrysomelidae are commonly known as leaf beetles, and include over 37,000 (and probably at least 50,000) species in more than 2,500 genera, making up 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 the 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. Adult and larval leaf beetles feed on all sorts of plant tissue, and all species are fully herbivorous. Many are serious pests of cultivated plants, fo ...

Integrated Taxonomic Information System
The Integrated Taxonomic Information System (ITIS) is an American partnership of federal agencies designed to provide consistent and reliable information on the taxonomy of biological species. ITIS was originally formed in 1996 as an interagency group within the US federal government, involving several US federal agencies, and has now become an international body, with Canadian and Mexican government agencies participating. The database draws from a large community of taxonomic experts. Primary content staff are housed at the Smithsonian National Museum of Natural History and IT services are provided by a US Geological Survey facility in Denver. The primary focus of ITIS is North American species, but many biological groups exist worldwide and ITIS collaborates with other agencies to increase its global coverage. Reference database ITIS provides an automated reference database of scientific and common names for species. As of May 2016, it contains over 839,000 scientific nam ...

Aposematism
Aposematism is the Advertising in biology, advertising by an animal to potential predation, predators that it is not worth attacking or eating. This unprofitability may consist of any defences which make the prey difficult to kill and eat, such as toxicity, venom, foul taste or smell, sharp spines, or aggressive nature. These advertising signals may take the form of conspicuous animal coloration, coloration, sounds, odours, or other perception, perceivable characteristics. Aposematic signals are beneficial for both predator and prey, since both avoid potential harm. The term was coined in 1877 by Edward Bagnall Poulton for Alfred Russel Wallace's concept of warning coloration. Aposematism is exploited in Müllerian mimicry, where species with strong defences evolve to resemble one another. By mimicking similarly coloured species, the warning signal to predators is shared, causing them to learn more quickly at less of a cost. A genuine aposematic signal that a species actually ...

Beetles Described In 1855
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 har ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
