August Holmgren (zoologist)
August Emil Algot Holmgren (10 November 1829 – 30 December 1888) was a Swedish entomologist mainly interested in the Hymenoptera, especially Ichneumonidae The Ichneumonidae, also known as ichneumon wasps, ichneumonid wasps, ichneumonids, or Darwin wasps, are a family of parasitoid wasps of the insect order Hymenoptera. They are one of the most diverse groups within the Hymenoptera with roughly 25 .... He was professor in the Forstakademie in Stockholm. Holmgren was the author of: *''Hymenoptera, species novas descripsit. Kongliga Svenska Fregatten Eugenies resa omkring Jordeni under befäl af C.A. Virgen Aren'' 1851–53.

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sawfly
Sawflies are wasp-like insects that are in the suborder Symphyta within the order Hymenoptera, alongside ants, bees, and wasps. The common name comes from the saw-like appearance of the ovipositor, which the females use to cut into the plants where they lay their eggs. The name is associated especially with the Tenthredinoidea, by far the largest superfamily in the suborder, with about 7,000 known species; in the entire suborder, there are 8,000 described species in more than 800 genera. Symphyta is paraphyletic, consisting of several basal groups within the order Hymenoptera, each one rooted inside the previous group, ending with the Apocrita which are not sawflies. The primary distinction between sawflies and the Apocrita – the ants, bees, and wasps – is that the adults lack a "wasp waist", and instead have a broad connection between the abdomen and the thorax. Some sawflies are Batesian mimics of wasps and bees, and the ovipositor can be mistaken for a stinger. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (taxonomy)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community fo ...

Argidae
Argidae, commonly known as the argid sawflies, is a large family of sawflies, containing some 800 species worldwide, primarily in tropical regions. The larvae are phytophagous, and commonly can be found feeding (and often pupating) in groups, though very few attain pest status. Description The family is distinguished from all other Symphyta by the reduction of the antenna to three segments, flagellomeres; the last one is elongated often shaped like a tuning fork in males. Distribution Species of this family are mainly found in the Neotropical region and in sub-Saharan Africa; however, this family is globally distributed. Genera Argidae contains the following genera, split between its two subfamilies: * Arginae ** '' Antargidium'' ** '' Arge'' ** '' Asiarge'' ** '' Brevisceniana'' ** '' Kokujewia'' ** '' Mioarge'' ** '' Pseudarge'' ** '' Scobina'' ** '' Sjoestedtia'' ** '' Spinarge'' ** '' Triarge'' ** '' Zhuhongfuna'' * Sterictiphorinae ** '' Acrogymn ...

Leaf Miner
A leaf miner is any one of numerous species of insects in which the larval stage lives in, and eats, the leaf tissue of plants. The vast majority of leaf-mining insects are moths (Lepidoptera), sawflies (Symphyta, a paraphyletic group which Apocrita (wasps, bees and ants) evolved from), and flies (Diptera). Some beetles also exhibit this behavior. Like woodboring beetles, leaf miners are protected from many predators and plant defenses by feeding within the tissues of the leaves, selectively eating only the layers that have the least amount of cellulose. When consuming ''Quercus robur'' (English oak), they also selectively feed on tissues containing lower levels of tannin, a deterrent chemical produced in great abundance by the tree. The pattern of the feeding tunnel and the layer of the leaf being mined is often diagnostic of the insect responsible, sometimes even to species level. The mine often contains frass, or droppings, and the pattern of frass deposition, mine sha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Purslane
''Portulaca oleracea'' (common purslane, also known as little hogweed, or pursley) is a succulent plant in the family Portulacaceae. Description The plant may reach in height. It has smooth, reddish, mostly prostrate stems, and the leaves, which may be Alternate leaf, alternate or opposite leaf, opposite, are clustered at stem joints and ends. The yellow flowers have five regular parts and are up to wide. Depending upon rainfall, the flowers appear at any time during the year. The flowers open singly at the center of the leaf cluster for only a few hours on sunny mornings. The tiny seeds are formed in a pod that opens when the seeds mature. Purslane has a taproot with fibrous secondary roots and can tolerate poor soil and drought. The fruits are many-seeded capsules. The seed set is considerable; one plant can develop up to 193,000 seeds. The seeds germinate optimally at a temperature above 25 °C; they are light germinators, with even a soil cover of 5 mm having a ...

Taxa Named By August Holmgren
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
