Nils Samuel Swederus
Nils Samuel Swederus also Svederus (24 August 1751 – 1833) was a Swedish naturalist. His parents were Sigtuna Magnus Svederus and Anna Maria Christiernin. Nils Samuel Swederus studied theology and other disciplines at the University of Uppsala. He was ordained in 1780 and became a ''hofpredikanten'' or Royal Court chaplain in 1782. From 1784 to 1786 he made scientific trips to several European countries—to England, France, Belgium and the Netherlands. In 1789 he became Vicar of Nasby and Ervalla parishes and dean of Fellingsbro. Nils Samuel Swederus was especially interested in entomology and was elected to membership of several learned societies in Sweden and abroad. These included the Royal Swedish Academy of Sciences. He was married to Anna Margareta Oberg. Works *1787 Fortsättning af Beskrifningen på 50 nya Species af Insecter. ''Kongliga Vetenskaps Academiens Nya Handlingar'' 8 (10–12): 276–290.

Blister Beetle
Blister beetles are beetles of the family Meloidae, so called for their defensive secretion of a blistering agent, cantharidin. About 7,500 species are known worldwide. Many are conspicuous and some are aposematically colored, announcing their toxicity to would-be predators. Description Blister beetles are hypermetamorphic, going through several larval stages, the first of which is typically a mobile triungulin. The larvae are insectivorous, mainly attacking bees, though a few feed on grasshopper eggs. While sometimes considered parasitoids, in general, the meloid larva apparently consumes the immature host along with its provisions, and can often survive on the provisions alone; thus it is not an obligatory parasitoid, but rather a facultative parasitoid, or simply a kleptoparasite. The adults sometimes feed on flowers and leaves of plants of such diverse families as the Amaranthaceae, Asteraceae, Fabaceae, and Solanaceae. Cantharidin, a poisonous chemical that causes b ...

Galápagos Islands
The Galápagos Islands ( es, Islas Galápagos) are an archipelago of volcanic islands in the Eastern Pacific, located around the Equator west of the mainland of South America. They form the Galápagos Province of the Republic of Ecuador, with a population of slightly over 33,000 (2020). The province is divided into the Cantons of Ecuador, cantons of San Cristóbal Island, San Cristóbal, Santa Cruz Island (Galápagos), Santa Cruz, and Isabela Island (Galápagos), Isabela, the three most populated islands in the chain. The Galápagos are famous for their large number of Endemism, endemic species, which were studied by Charles Darwin in the 1830s and inception of Darwin's theory, inspired his theory of evolution by means of natural selection. All of these islands are protected as part of Ecuador's Galápagos National Park and Galápagos Marine Reserve, Marine Reserve. Thus far, there is no firm evidence that Polynesian expansion, Polynesians or the indigenous peoples of South Am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brood Parasite
Brood parasites are animals that rely on others to raise their young. The strategy appears among birds, insects and fish. The brood parasite manipulates a host, either of the same or of another species, to raise its young as if it were its own, usually using egg mimicry, with eggs that resemble the host's. The evolutionary strategy relieves the parasitic parents from the investment of rearing young. This benefit comes at the cost of provoking an evolutionary arms race between parasite and host as they coevolve: many hosts have developed strong defenses against brood parasitism, such as recognizing and ejecting parasitic eggs, or abandoning parasitized nests and starting over. It is less obvious why most hosts do care for parasite nestlings, given that for example cuckoo chicks differ markedly from host chicks in size and appearance. One explanation, the mafia hypothesis, proposes that parasitic adults retaliate by destroying host nests where rejection has occurred; there ...

Xylocopa Darwini
''Xylocopa darwini'', the Galápagos carpenter bee, is the only native species of bee in the Galápagos Islands, to which it is endemic. Altogether, only three species of bee are found in the islands. This species found on 75% of the largest islands. It is sexually dimorphic and is known for its complex behavior. As the only native bee, ''Xylocopa darwini'' serves as an important primary pollinator within the plant-pollinator network of the archipelago. Description The leaf-cutter bee and the wool carder bee are introduced, making the Galápagos carpenter bee the only native species. As a sexually dimorphic species, the male and female bees look different. The female bee is dark and shiny with black setae, and is commonly found throughout the year. The male is rarer, with a black abdomen and yellow-brown setae. A rare specimen in the Smithsonian collection exhibits gynandromorphism, with a visually female left side and a visually male right side. Distribution Galapagos ...

Beetles Described In 1787
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 exoske ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
