Ernst Friedrich Germar
Ernst Friedrich Germar (3 November 1786 – 8 July 1853) was a German professor and director of the Mineralogical Museum at Halle. As well as being a mineralogist he was interested in entomology and particularly in the Coleoptera and Hemiptera. He monographed the heteropteran family Scutelleridae. In 1845, he was elected a foreign member of the Royal Swedish Academy of Sciences. Published works Amongst Germar's publications are: *Species Cicadarium enumeratae et sub genera distributae. ''Thon's Entomologisches Archiv''. (2)2: 37–57, pl. 1 (1830). *Observations sur plusieurs espèces du genre Cicada, ''Latr. Rev. Entomol. Silbermann'' 2: 49–82, pls. 19-26 (1834). *Ueber die Elateriden mit häutigen Anhängen der Tarsenglieder. Z. Entomol. (Germar) 1: 193-236 (1839) (1839). *Bemerkungen über Elateriden. ''Z. Entomol. (Breslau)'' 5: 133-192 (1844). *Beiträge zur insektenfauna von Adelaide. ''Linn. Entomol.'' 3: 153-247 (1848). *Fauna Insectorum Europae. There were 24 fas ...

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, f ...

Donaciinae
The Donaciinae are a subfamily of the leaf beetles, or Chrysomelidae, characterised by distinctly long antennae. They are found in mainly the Northern Hemisphere, with some species found in the Southern Hemisphere. Life cycle Female Donaciinae lay eggs between aquatic plant stems and leaf sheaths. When larvae hatch they are aquatic, and attach themselves to underwater stems and roots of their plant hosts, primarily '' Potamogeton'', for food and oxygen. Adults live in vegetation bordering ponds, marshes, lakes, and brackish water environments. While most Donaciinae have the ability to fly, fully aquatic and flightless species such as '' Macroplea mutica'' exhibit the ability to disperse long distance by surviving the passage though the gut of water birds. Genera These six genera belong to the subfamily Donaciinae: * '' Donacia'' Fabricius, 1775 * '' Donaciella'' Reitter, 1920 * '' Macroplea'' Samouelle, 1819 * '' Neohaemonia'' Székessy, 1941 * '' Plateumaris'' Thomson, 1859 ...

Palearctic
The Palearctic or Palaearctic is the largest of the eight biogeographic realms of the Earth. It stretches across all of Eurasia north of the foothills of the Himalayas, and North Africa. The realm consists of several bioregions: the Euro-Siberian region; the Mediterranean Basin; the Sahara and Arabian Deserts; and Western, Central and East Asia. The Palaearctic realm also has numerous rivers and lakes, forming several freshwater ecoregions. The term 'Palearctic' was first used in the 19th century, and is still in use as the basis for zoogeographic classification. History In an 1858 paper for the ''Proceedings of the Linnean Society'', British zoologist Philip Sclater first identified six terrestrial zoogeographic realms of the world: Palaearctic, Aethiopian/Afrotropic, Indian/Indomalayan, Australasian, Nearctic, and Neotropical. The six indicated general groupings of fauna, based on shared biogeography and large-scale geographic barriers to migration. Alfred Wallace a ...

Beetles Of Asia
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 hard exos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
