Johan Wilhelm Dalman
Johan Wilhelm Dalman (November 4, 1787 in Hinseberg, Västmanland – July 11, 1828 in Stockholm) was a Swedish physician and a naturalist. He first studied at Christiansfeld in Schleswig-Holstein then at the University of Lund and the University of Uppsala. He was mainly interested in entomology and botany. He received his degree in 1816 then his doctorate in 1817 from the University of Uppsala. Dalman became librarian of the Royal Swedish Academy of Sciences, a member of the Academy in 1821, then director of the zoological garden, then demonstrator in botany at the Karolinska Institutet of Stockholm. Dalman's main interest lay in entomology and botany, but he also became involved in the systematics and taxonomy of trilobites. In 1771 Johann Ernst Immanuel Walch (1725-1778) first used the term trilobite. Researchers had tried to link trilobites to extant groups such as chitons and various arthropods. Before Walch’s work this had led to great confusion. By 1820 th ...

Juan Brèthes
Juan (Jean) Brèthes, also known as Frère Judulien Marie or Juan Brethes (24 February 1871, in Saint-Sever, Landes – 2 July 1928, in Buenos Aires) was an Argentine scientist, naturalist, entomologist, ornithologist, zoologist and geologist. He was the first entomologist of the National Museum, today known as the Argentine Museum of Natural Sciences. He was a close collaborator of Florentino Ameghino Florentino Ameghino (born Giovanni Battista Fiorino Giuseppe Ameghino September 19, 1853 – August 6, 1911) was an Argentine naturalist, paleontologist, anthropologist and zoologist, whose fossil discoveries on the Argentine Pampas, especially ..., and translated several of his works into French. Thanks to his intense activity, he systematized a large number of Latin American insect species. He was a precursor in the fight against agricultural pests at a time when insecticides had not been developed to combat them. His arrival in Buenos Aires Juan Brèthes was born on ...

Hymenoptera Genera
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they mature. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek πτερόν (''pteron'') for wing. The Ancient Greek ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings. However, a key characteristic of this order is that the hindwings are co ...

Ectoparasitoid
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 l ...

Natural History Museum, London
The Natural History Museum in London is a museum that exhibits a vast range of specimens from various segments of natural history. It is one of three major museums on Exhibition Road in South Kensington, the others being the Science Museum and the Victoria and Albert Museum. The Natural History Museum's main frontage, however, is on Cromwell Road. The museum is home to life and earth science specimens comprising some 80 million items within five main collections: botany, entomology, mineralogy, palaeontology and zoology. The museum is a centre of research specialising in taxonomy, identification and conservation. Given the age of the institution, many of the collections have great historical as well as scientific value, such as specimens collected by Charles Darwin. The museum is particularly famous for its exhibition of dinosaur skeletons and ornate architecture—sometimes dubbed a ''cathedral of nature''—both exemplified by the large ''Diplodocus'' cast that domina ...

Torymidae
Torymidae is a family of wasps in the superfamily Chalcidoidea. Most species in this family are small with attractive metallic coloration, and females generally have long ovipositors. Many are parasitoids on gall-forming insects, and some are phytophagous (plant-eating) species, sometimes using the galls formed by other insects. Over 960 species in about 70 genera are found worldwide. They are best recognized in that they are one of the few groups of Chalcidoidea Chalcid wasps (, , for their metallic colour) are insects within the superfamily Chalcidoidea, part of the order Hymenoptera.

Systematics The family was first described by Walker in 1833 and the infrafamiliar classification has been revised several times. A number of subfamilies were created within Torymidae, some of which have since been transferred to other fam ...

Chalcid Wasp
Chalcid wasps (, , for their metallic colour) are insects within the superfamily Chalcidoidea, part of the order Hymenoptera. The superfamily contains some 22,500 known species, and an estimated total diversity of more than 500,000 species, meaning the vast majority have yet to be discovered and described. The name "chalcid" is often confused with the name "chalcidid", though the latter refers strictly to one constituent family, the Chalcididae, rather than the superfamily as a whole; accordingly, most recent publications (e.g.,) use the name "chalcidoid" when referring to members of the superfamily. Most chalcid wasps are parasitoids of other insects, though other life styles are known, with the herbivorous fig wasps acting as pollinators. Various species are used as biological pest control agents or in scientific research. Description Chalcidoids are generally small wasps, averaging 1.5 mm in length and usually being less than 3 mm. The body is often metallic in colour. Th ...
