Arnold Förster
Arnold Förster (20 January 1810 – 13 August 1884) was a German entomologist, who worked mainly on Coleoptera and Hymenoptera. Life Arnold Förster was born on 20 January 1810 in Aachen, Germany, where he died on 12 August 1884. He was Oberlehrer, or an upper teacher, in Aachen for his entire adult life. He worked ceaselessly on entomology, paying particular attention to Coleoptera and Hymenoptera. He was a pioneering author on Hymenoptera. Work Selection *''Hymenopterologische Studien'' I .

Hymenoptera
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 reach adulthood. 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 hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Braconidae
The Braconidae are a family of parasitoid wasps. After the closely related Ichneumonidae, braconids make up the second-largest family in the order Hymenoptera, with about 17,000 recognized species and many thousands more undescribed. One analysis estimated a total between 30,000 and 50,000, and another provided a narrower estimate between 42,000 and 43,000 species. Classification The Braconidae are currently divided into about 47 subfamilies and over 1000 genera, which include ''Aerophilus'', ''Aleiodes'', ''Apanteles'', ''Asobara'', ''Bracon (wasp), Bracon'', ''Cenocoelius'', ''Chaenusa'', ''Chorebus'', ''Cotesia'', ''Dacnusa'', ''Diachasma'', ''Dimeris'', ''Microgaster'', ''Opius'', ''Parapanteles'', ''Phaenocarpa'', ''Spathius'', and ''Syntretus.'' These fall into two major groups, informally called the cyclostomes and noncyclostomes. In cyclostome braconids, the Labrum (arthropod mouthpart), labrum and the lower part of the Clypeus (arthropod anatomy), clypeus are concave ...

Ectoedemia Argyropeza
''Ectoedemia argyropeza '' is a moth of the family Nepticulidae. It is a widespread species, with a Holarctic distribution. Description The wingspan is 7 mm. The head is ochreous-yellow with a whitish collar. The antennal eyecaps are also whitish. The forewings are dark fuscous with a small costal spot before middle, and a larger dorsal spot before the tornus whitish; outer half of cilia whitish. The hindwings are grey. Taxonomy The name history is complex. Adults are on wing from May to June. It is a parthenogenetic species, with males being extremely rare. The larvae feed on aspen (''Populus tremula'') and quaking aspen (''Populus tremuloides'' (ssp. ''downesi'')). They mine the leaves of their host plant. Subspecies *''Ectoedemia argyropeza argyropeza'' *''Ectoedemia argyropeza downesi'' Wilkinson and Scoble, 1979 (North America) Distribution It is found in most of Europe, as well as North America.

Populus Nigra
''Populus nigra'', the black poplar, is a species of Populus sect. Aigeiros, cottonwood poplar, the type species of section ''Aigeiros'' of the genus ''Populus'', native to Europe, southwest and central Asia, and northwest Africa.Flora Europaea''Populus nigra''/ref> Description Black poplars are medium- to large-sized deciduous trees, reaching 20–30 m, and rarely 40 m tall. Their leaf, leaves are diamond-shaped to triangular, 5–8 cm long and 6–8 cm broad, and green on both surfaces.Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins. . Normally, their trunks achieve up to 1.5 m in diameter, but some unusual individual trees in France have grown old enough to have much larger trunks – more than 3 metres DBH (Diameter at breast height, Diameter at Breast Height). The species is Wiktionary:dioecious, dioecious (male and female flowers are on different plants), with flowers in catkins and pollination achieved by the wind. The black poplar grow ...

Parasitic Wasps
Parasitoid wasps are a large group of hymenopteran superfamilies, with all but the wood wasps ( Orussoidea) being in the wasp-waisted Apocrita. As parasitoids, they lay their eggs on or in the bodies of other arthropods, sooner or later causing the death of these hosts. Different species specialise in hosts from different insect orders, most often Lepidoptera, though some select beetles, flies, or bugs; the spider wasps ( Pompilidae) exclusively attack spiders. Parasitoid wasp species differ in which host life-stage they attack: eggs, larvae, pupae, or adults. They mainly follow one of two major strategies within parasitism: either they are endoparasitic, developing inside the host, and koinobiont, allowing the host to continue to feed, develop, and moult; or they are ectoparasitic, developing outside the host, and idiobiont, paralysing the host immediately. Some endoparasitic wasps of the superfamily Ichneumonoidea have a mutualistic relationship with polydnaviruses, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insects Described In 1851
Insects (from Latin ') are Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (Insect morphology#Head, head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes, and a pair of antenna (biology), antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a insect brain, brain and a ventral nerve cord. Most insects reproduce Oviparous, by laying eggs. Insects Respiratory system of insects, breathe air through a system of Spiracle (arthropods), paired openings along their sides, connected to Trachea#Invertebrates, small tubes that take air directly to the tissues.
