Johann Karl Wilhelm Illiger
Johann Karl Wilhelm Illiger (19 November 1775 – 10 May 1813) was a German entomologist and zoologist. Illiger was the son of a merchant in Braunschweig. He studied under the entomologist Johann Christian Ludwig Hellwig, Johann Hellwig, and later worked on the zoological collections of Johann Centurius Hoffmannsegg. Illiger was professor and director of the "zoological museum" (which is the Natural History Museum, Berlin, Natural History Museum of Berlin in the present day) from its formation in 1810 until his death. He was the author of ''Prodromus systematis mammalium et avium'' (1811), which was an overhaul of the Carl Linnaeus, Linnaean system. It was a major influence on the adoption of the concept of the Family (biology), family. He also edited the ''Magazin für Insektenkunde'', widely known as "Illiger's Magazine". In 1811 he introduced the taxonomic order Proboscidea for elephants, the American Mastodon, American mastodon and the woolly mammoth. He also described the ...

Beetle
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 e ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Dytiscidae
The Dytiscidae – based on the Greek ''dytikos'' (δυτικός), "able to dive" – are the predaceous diving beetles, a family of water beetles. They occur in virtually any freshwater habitat around the world, but a few species live among leaf litter. The adults of most are between long, though much variation is seen between species. The European ''Dytiscus latissimus'' and Brazilian ''Megadytes ducalis'' are the largest, reaching up to and respectively. In contrast, the smallest is likely the Australian ''Limbodessus atypicali'' of subterranean waters, which only is about long. Most are dark brown, blackish, or dark olive in color with golden highlights in some subfamilies. The larvae are commonly known as water tigers due to their voracious appetite. They have short, but sharp mandibles and immediately upon biting, they deliver digestive enzymes into prey to suck their liquefied remains. The family includes more than 4,000 described species in numerous genera. ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
