Aulacoscelidinae
The beetle subfamily Aulacoscelidinae (sometimes misspelled "Aulacoscelinae") is a small, uncommonly-encountered group presently classified within the family Orsodacnidae, historically placed as a subfamily of Chrysomelidae, or sometimes classified as a separate family Aulacoscelidae. There are only 19 species, mostly Neotropical in distribution, and their larva A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The ...l habits are unknown.

Chrysomelidae
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, ...

Carl Gustaf Thomson
Carl Gustaf Thomson (13 October 1824, in Malmöhus County, Malmöhus – 20 September 1899, in Lund) was a Sweden, Swedish entomologist. Thomson became a student in the University of Lund in 1843, graduated in 1850 and became associate professor of zoology there in 1857. In 1862 he became the curator of the entomological department of the Zoological Museum and in 1864 became a lecturer in entomology as well. An 1872 scholarship enabled him to travel to the continent for scientific study. He was offered the post of Director of the Entomological Museum in Berlin, but he declined. Carl Gustaf Thomson was the author of ''Coleoptera Scandinaviae'' (ten volumes, 1859–68), ''Skandinaviens inseckta'' (1862), ''Scandinavia Hymenoptera'' (five volumes, 1871–79) and ''Opuscula Entomologica'' (22 bands, 1869–97) He also published descriptions of the insects collected on the voyage of the Fregatten Eugenies (HSwMS Eugenie), the first Swedish vessel to circumnavigate the world.

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Oxypeltidae
The Oxypeltidae are a small family belonging to the superfamily Chrysomeloidea, widespread in the Andean region of Chile and Argentina. They have traditionally been considered a group within the Cerambycidae. Description The body is massive and characterised by metallic colour, bluish or green on the head and prothorax, and red on the elytra. Their antennae and legs have a blue metallic colour. The head, round and small, has two robustly toothed antennae, the pronotum is furnished with longitudinal crests, and the elytra, covered by strong puncture, are bidentate at the apex. The posterior wings, membranous, have an unusual violet colour, while they are transparent or brownish in cerambycids. Biology The larvae, typically xylophagous, attack trees of the genus ''Nothofagus'', the vicariant of beeches in the Southern Hemisphere. The adults are diurnal and can often be found on leaves. Systematics They have always been a mystery for specialists since these insects do not show ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southern subregion of a single continent called America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island ( dependency of Norway), Pa ...

Early Cretaceous
The Early Cretaceous ( geochronological name) or the Lower Cretaceous (chronostratigraphic name), is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from 145 Ma to 100.5 Ma. Geology Proposals for the exact age of the Barremian-Aptian boundary ranged from 126 to 117 Ma until recently (as of 2019), but based on drillholes in Svalbard the defining early Aptian Oceanic Anoxic Event 1a (OAE1a) was carbon isotope dated to 123.1±0.3 Ma, limiting the possible range for the boundary to c. 122–121 Ma. There is a possible link between this anoxic event and a series of Early Cretaceous large igneous provinces (LIP). The Ontong Java-Manihiki-Hikurangi large igneous province, emplaced in the South Pacific at c. 120 Ma, is by far the largest LIP in Earth's history. The Ontong Java Plateau today covers an area of 1,860,000 km2. In the Indian Ocean another LIP began to form at c. 120 Ma, the Kerguelen P ...
