Oscar Ringdahl
Oscar Ringdahl (1885–1966) was a Swedish entomologist who specialised in Diptera and Trichoptera. Ringdahl described many new species from Sweden and Lappland. Parts of his personal collection are in the Swedish Museum of Natural History and Lund University Zoology Museum (Lunds Universitet Zoologiska museet), Lund. Works Partial list:: *Ringdahl, O.

Entomologist
Entomology () is the scientific study of insects, a branch of zoology. In the past the term "insect" was less specific, and historically the definition of entomology would also include the study of animals in other arthropod groups, such as arachnids, myriapods, and crustaceans. This wider meaning may still be encountered in informal use. Like several of the other fields that are categorized within zoology, entomology is a taxon-based category; any form of scientific study in which there is a focus on insect-related inquiries is, by definition, entomology. Entomology therefore overlaps with a cross-section of topics as diverse as molecular genetics, behavior, neuroscience, biomechanics, biochemistry, systematics, physiology, developmental biology, ecology, morphology, and paleontology. Over 1.3 million insect species have been described, more than two-thirds of all known species. Some insect species date back to around 400 million years ago. They have many kinds of intera ...

Diptera
Flies are insects of the order Diptera, the name being derived from the Greek δι- ''di-'' "two", and πτερόν ''pteron'' "wing". Insects of this order use only a single pair of wings to fly, the hindwings having evolved into advanced mechanosensory organs known as halteres, which act as high-speed sensors of rotational movement and allow dipterans to perform advanced aerobatics. Diptera is a large order containing an estimated 1,000,000 species including horse-flies, crane flies, hoverflies and others, although only about 125,000 species have been described. Flies have a mobile head, with a pair of large compound eyes, and mouthparts designed for piercing and sucking (mosquitoes, black flies and robber flies), or for lapping and sucking in the other groups. Their wing arrangement gives them great maneuverability in flight, and claws and pads on their feet enable them to cling to smooth surfaces. Flies undergo complete metamorphosis; the eggs are often laid on the l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trichoptera
The caddisflies, or order Trichoptera, are a group of insects with aquatic larvae and terrestrial adults. There are approximately 14,500 described species, most of which can be divided into the suborders Integripalpia and Annulipalpia on the basis of the adult mouthparts. Integripalpian larvae construct a portable casing to protect themselves as they move around looking for food, while Annulipalpian larvae make themselves a fixed retreat in which they remain, waiting for food to come to them. The affinities of the small third suborder Spicipalpia are unclear, and molecular analysis suggests it may not be monophyletic. Also called sedge-flies or rail-flies, the adults are small moth-like insects with two pairs of hairy membranous wings. They are closely related to the Lepidoptera (moths and butterflies) which have scales on their wings; the two orders together form the superorder Amphiesmenoptera. The aquatic larvae are found in a wide variety of habitats such as streams, river ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Swedish Museum Of Natural History
The Swedish Museum of Natural History ( sv, Naturhistoriska riksmuseet, literally, the National Museum of Natural History), in Stockholm, is one of two major museums of natural history in Sweden, the other one being located in Gothenburg. The museum was founded in 1819 by the Royal Swedish Academy of Sciences, but goes back to the collections acquired mostly through donations by the academy since its foundation in 1739. These collections had first been made available to the public in 1786. The museum was separated from the Academy in 1965. One of the keepers of the collections of the academy during its earlier history was Anders Sparrman, a student of Carl Linnaeus and participant in the voyages of Captain James Cook. Another important name in the history of the museum is the zoologist, paleontologist and archaeologist Sven Nilsson, who brought the previously disorganised zoological collections of the museum into order during his time as keeper (1828–1831) before returning t ...

Lund
Lund (, , ) is a city in the southern Swedish provinces of Sweden, province of Scania, across the Øresund, Öresund strait from Copenhagen. The town had 91,940 inhabitants out of a municipal total of 121,510 . It is the seat of Lund Municipality, Scania County. The Øresund Region, Öresund Region, which includes Lund, is home to more than 4.1 million people. Archeologists date the foundation of Lund to around 990, when Scania was part of Denmark. From 1103 it was the seat of the Catholic Metropolitan Archdiocese of Lund, and the towering Lund Cathedral, built circa 1090–1145, still stands at the centre of the town. Denmark ceded the city to Sweden in the Treaty of Roskilde in 1658, and its status as part of Sweden was formalised in 1720. Lund University, established in 1666, is one of Scandinavia's oldest and largest institutions for education and research. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peder Nielsen
Peder Nielsen (1 February 1893 – 16 March 1975) was a Danish librarian and entomologist who specialised in the order Diptera especially Nematocera. Peder Kristian Nielsen was born at Silkeborg, Denmark. He received training at the Statens Bogsamlingskomité in Copenhagen and in 1917, he became an assistant at Silkeborg library. Over his more than 40-year career, he came to influence the development in the local library system. Peder Nielsen resigned as library manager in 1958. In the field of entomology, he studied mosquitoes, crane flies, gnats and fungal mosquitoes. His crane fly (''stankelben'') collection and other two-wing insects were given to the University of Copenhagen Zoological Museum The Copenhagen Zoological Museum (Danish: ''Zoologisk Museum'') is a part of the Natural History Museum of Denmark, which is affiliated with the University of Copenhagen.
