Conostigmus
''Conostigmus'' is a genus of parasiotoid wasps belonging to the superfamily Ceraphronoidea. It is the second-largest genus within the family Megaspilidae (Johnson & Musetti 2004). The genus has a worldwide distribution with over 170 extant species. Though it is the second largest genus within Megaspilidae, little is known about its life history. A few species are known to be ectoparasitoids, though it is likely that the genus also contains endoparasitoids as well, since the sister genus ''Dendrocerus ''Dendrocerus'' is a genus of megaspilid wasps in the family Megaspilidae The Megaspilidae are a small hymenopteran family with 13 genera in two subfamilies, and some 450 known species, with a great many species still undescribed.

Megaspilidae
The Megaspilidae are a small hymenopteran family with 13 genera in two subfamilies, and some 450 known species, with a great many species still undescribed. It is a poorly known group as a whole, though most are believed to be parasitoids (especially of sternorrhynchan Hemiptera), and a few hyperparasitoids. Many are found in the soil, and of these, a number are wingless. The family is distinguished from the closely related Ceraphronidae by having a very large stigma in the wing, a relatively constricted metasomal petiole, and three grooves in the mesoscutum. The largest genus within Megaspilidae is '' Dendrocerus''. The second largest genus is ''Conostigmus''.

Anders Gustaf Dahlbom
Anders Gustaf Dahlbom (3 March 1806 – 3 May 1859) was a Swedish entomologist. Dahlbom was born in Härberga parish in Östergötland County, son of a military surgeon. He matriculated at Lund University in 1825, completed his filosofie magister degree in 1829, became a docent of natural history in 1830, acting adjunct of entomology in 1841, adjunct in 1843 and keeper of the Entomological collections and professor extraordinary in 1857. Supported by public funds, he made several research journeys, especially to northern Sweden and the mountain regions, where he first accompanied his teacher, the dipterologist Johan Wilhelm Zetterstedt, as well as to other parts of the country and abroad, and published his observations in various works, most important of which is ''Hymenoptera europaea praecipue borealia'' (1843–1853), a foundational work on the hymenoptera Hymenoptera is a large order (biology), order of insects, comprising the sawfly, sawflies, wasps, bees, and a ...

William Harris Ashmead
William Harris Ashmead was an American entomologist born on 19 September 1855 at Philadelphia. He died 17 October 1908 at Washington D.C. After his studies in Philadelphia, Ashmead worked for the publisher J. B. Lippincott & Co. Later, he settled in Florida where he formed his own publishing house devoted to agriculture. He also launched the '' Florida Dispatch'', an agricultural weekly magazine which included a headed section devoted to injurious insects. In 1879, he began writing papers for scientific publications and, in 1887, he became a field entomologist working for the Ministry for the Agriculture of Florida. The following year, he became entomologist at the Agricultural Research station of Lake City. In 1889, he worked again for the Ministry for Agriculture. The following year, and for two years, he traveled, in particular to Germany, to perfect his entomological knowledge. In 1895, he obtained the post of conservation assistant in the Department of Entomology of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceraphronoidea
The Ceraphronoidea are a small hymenopteran superfamily that includes only two families, and a total of some 800 species, though a great many species are still undescribed. It is a poorly known group as a whole, and most are believed to be parasitoid or hyperparasitoids. The two families are unified by several characters, the most visible of which is their wing venation is greatly reduced in a very specific and unique way; the costal and radial veins have fused so no costal cell is present, a short break occurs at the stigma, and the only vein in the wing membrane itself is the radial sector, which is short and curved, arising from the stigma. The taxon was erected by Alexander Henry Haliday. Some fossil families that were formerly assigned to this group have since been reassigned elsewhere including Aptenoperissidae, Radiophronidae and Stigmaphronidae.

Endoparasitoids
In evolutionary ecology, a parasitoid is an organism that lives in close association with its host at the host's expense, eventually resulting in the death of the host. Parasitoidism is one of six major evolutionary strategies within parasitism, distinguished by the fatal prognosis for the host, which makes the strategy close to predation. Among parasitoids, strategies range from living inside the host (''endoparasitism''), allowing it to continue growing before emerging as an adult, to paralysing the host and living outside it (''ectoparasitism''). Hosts can include other parasitoids, resulting in hyperparasitism; in the case of oak galls, up to five levels of parasitism are possible. Some parasitoids influence their host's behaviour in ways that favour the propagation of the parasitoid. Parasitoids are found in a variety of taxa across the insect superorder Endopterygota, whose complete metamorphosis may have pre-adapted them for a split lifestyle, with parasitoid lar ...
