Stylopidae
Stylopidae is a family of twisted-winged insects in the order Strepsiptera. There are about 15 genera and more than 330 described species in Stylopidae. Members of Stylopidae are parasitic insects. Host insects of this family that are afflicted are referred to as being "stylopized". Stylopidae are associated primarily with wasps and bees but are known to also use members of Blattodea, Mantodea, Orthoptera, Hemiptera, Diptera, and other Hymenoptera as hosts. Stylopized hosts often display a variety of physical and behavioral changes. Life cycle As with others in the order Strepsiptera, Stylopidae larvae called triungulins enter their host and develop inside it. Females will remain inside the host. When females are ready to breed, they will push their head and brood canal opening, which is located just behind their head, out between the host insect's sclerites. Females draw males with pheromones who mate with them by means of the exposed brood canal. The eggs will hatch inside ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strepsiptera
The Strepsiptera are an order of insects with eleven extant families that include about 600 described species. They are endoparasites in other insects, such as bees, wasps, leafhoppers, silverfish, and cockroaches. Females of most species never emerge from the host after entering its body, finally dying inside it. The early-stage larvae do emerge because they must find an unoccupied living host, and the short-lived males must emerge to seek a receptive female in her host. They are believed to be most closely related to beetles, from which they diverged 300–350 million years ago, but do not appear in the fossil record until the mid-Cretaceous around 100 million years ago. The order is not well known to non-specialists, and the nearest they have to a common name is stylops. The name of the order translates to "twisted wing"', giving rise to other common names used for the order, twisted-wing insects and twisted-winged parasites. Adult males are rarely observed, although specimen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xenos (insect)
''Xenos'' is a genus of insects belonging to the family Xenidae. The word derives from the Greek word for strange. A species of the genus is ''Xenos vesparum'', first described by Pietro Rossi in 1793. The females are permanent entomophagous endoparasites of ''Polistes'' paper wasps. They dwell their whole lives in the abdomens of wasps. Species These 33 species belong to the genus ''Xenos'': * ''Xenos afer'' Pasteels, 1950 (Africa) * ''Xenos americanus'' (Brèthes, 1923) (South America) * '' Xenos argentinus'' Brèthes, 1923 (South America) * '' Xenos boharti'' Hofmann, 1965 (South America) * '' Xenos bohlsi'' Hoffmann, 1914 (South America) * '' Xenos bonairensis'' Brèthes, 1923 (South America) * ''Xenos circularis'' Kifune & Maeta, 1985 (Asia) * '' Xenos colombiensis'' Cook, Mayorga-Ch & Sarmiento, 2020 * '' Xenos dianshuiwengi'' Yang, 1999 * '' Xenos formosanus'' Kifune & Maeta, 1985 (Asia) * ''Xenos hamiltoni'' Kathirithamby & Hughes, 2006 (Central America and Mexico) * ' ...

Stylops
''Stylops'' is a genus of obligately endoparasitic insects in the family Stylopidae. Hosts are typically members of the order Hymenoptera. The name "stylops", used without a capital "s", refers as a common name to any member of the order Strepsiptera, and not only the genus ''Stylops''. Description Males are 2-3 mm long and black with white wings. Females have no limbs and are only seen from their head and thorax poking out of the host bee. Larvae are triungulin. Life cycle ''Stylops'' larvae emerge from their host bee while the host gathers pollen from flowers. The larvae then attach to other bees in order to be carried back to the nest. At the nest, the ''Stylops'' larvae enter the bodies of bee larvae and develop along with their host. Adult males leave their hosts to mate with females, who remain inside their host and hatch their eggs there. Species Many including: * '' Stylops analis'' Perkins, 1918 * '' Stylops andrenaphilus'' Luna de Carvalho, 1974 * '' Stylops at ...

Halictoxenos
''Halictoxenos'' is a genus of insects belonging to the family Stylopidae. The genus was first described by Pierce in 1908. The species of this genus are found in Eurasia and Northern America Northern America is the northernmost subregion of North America. The boundaries may be drawn slightly differently. In one definition, it lies directly north of Middle America (including the Caribbean and Central America).Gonzalez, Joseph. 20 ....

William Kirby (entomologist)
William Kirby (19 September 1759 – 4 July 1850) was an English entomologist, an original member of the Linnean Society and a Fellow of the Royal Society, as well as a country rector, so that he was an eminent example of the "parson-naturalist". The four-volume ''Introduction to Entomology'', co-written with William Spence, was widely influential. Family origins and early studies Kirby was a grandson of the Suffolk topographer John Kirby (author of ''The Suffolk Traveller'') and nephew of artist-topographer Joshua Kirby (a friend of Thomas Gainsborough's). He was also a cousin of the children's author Sarah Trimmer. His parents were William Kirby, a solicitor, and Lucy Meadows. He was born on 19 September 1759 at Witnesham, Suffolk, and studied at Ipswich School and Caius College, Cambridge, where he graduated in 1781. Taking holy orders in 1782, he spent his entire working life in the peaceful seclusion of an English country parsonage at Barham in Suffolk, working at th ...

Sclerite
A sclerite (Greek , ', meaning "hard") is a hardened body part. In various branches of biology the term is applied to various structures, but not as a rule to vertebrate anatomical features such as bones and teeth. Instead it refers most commonly to the hardened parts of arthropod exoskeletons and the internal spicules of invertebrates such as certain sponges and soft corals. In paleontology, a scleritome is the complete set of sclerites of an organism, often all that is known from fossil invertebrates. Sclerites in combination Sclerites may occur practically isolated in an organism, such as the sting of a cone shell. Also, they can be more or less scattered, such as tufts of defensive sharp, mineralised bristles as in many marine Polychaetes. Or, they can occur as structured, but unconnected or loosely connected arrays, such as the mineral "teeth" in the radula of many Mollusca, the valves of Chitons, the beak of Cephalopod, or the articulated exoskeletons of Arthropoda.

Priabonian
The Priabonian is, in the ICS's geologic timescale, the latest age or the upper stage of the Eocene Epoch or Series. It spans the time between . The Priabonian is preceded by the Bartonian and is followed by the Rupelian, the lowest stage of the Oligocene. Stratigraphic definition The Priabonian Stage was introduced in scientific literature by Ernest Munier-Chalmas and Albert de Lapparent in 1893. The stage is named after the small hamlet of Priabona in the community of Monte di Malo, in the Veneto region of northern Italy. The base of the Priabonian Stage is at the first appearance of calcareous nannoplankton species ''Chiasmolithus oamaruensis'' (which forms the base of nanoplankton biozone NP18). An official GSSP was ratified in 2020, and was placed in the Alano di Piave section in Alano di Piave, Belluno, Italy. The top of the Priabonian Stage (the base of the Rupelian Stage and Oligocene Series) is at the extinction of foram genus ''Hantkenina''. Sometimes local rock ...

Baltic Amber
The Baltic region is home to the largest known deposit of amber, called Baltic amber or succinite. It was produced sometime during the Eocene epoch, but exactly when is controversial. It has been estimated that these forests created more than 100,000 tons of amber. Today, more than 90% of the world's amber comes from Kaliningrad Oblast of Russia. It is a major source of income for the region; the local Kaliningrad Amber Combine extracted 250 tonnes of it in 2014, 400 tonnes in 2015. "Baltic amber" was formerly thought to include amber from the Bitterfeld Lignite, brown coal mines in Saxony (Eastern Germany). Bitterfeld amber was previously believed to be only 20–22 million years old (Miocene), but a comparison of the animal inclusions in 2003 suggested that it was possibly Baltic amber that was redeposited in a Miocene deposit. Further study of insect taxa in the ambers has shown Bitterfeld amber to be from the same forest as the Baltic amber forest, but separately deposited f ...
