Diplolepis Polita
''Diplolepis polita'', known generally as the spiny leaf gall wasp, is a species of gall wasp in the family Cynipidae. It was first described by William Harris Ashmead in 1890. This species induces galls on several species of wild roses in North America, including Rosa arkansana and Rosa acicularis ''Rosa acicularis'' is a flowering plant in the Rosaceae family. It is commonly known as the prickly wild rose, prickly rose, bristly rose, wild rose or Arctic rose. It is a species of wild rose with a Holarctic distribution in northern regions o .... The galls are formed on the leaves in spring and early summer and are spherical with short spikes.

Gall Wasp
Gall wasps, also incorrectly called gallflies, are hymenopterans of the family Cynipidae in the wasp superfamily Cynipoidea. Their common name comes from the galls they induce on plants for larval development. About 1,300 species of this generally very small creature (1–8 mm) are known worldwide, with about 360 species of 36 different genera in Europe and some 800 species in North America. Features Like all Apocrita, gall wasps have a distinctive body shape, the so-called Petiole (insect anatomy), wasp waist. The first abdominal tergum (the propodeum) is conjoined with the Thorax (insect anatomy), thorax, while the second abdominal segment forms a sort of shaft, the Petiole (insect anatomy), petiole. The petiole connects with the gaster (insect anatomy), gaster, which is the functional abdomen in apocritan wasps, starting with the third abdominal segment proper. Together, the petiole and the gaster form the metasoma, while the thorax and the propodeum make up the mesosoma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
Gall
Galls (from the Latin , 'oak-apple') or ''cecidia'' (from the Greek , anything gushing out) are a kind of swelling growth on the external tissues of plants, fungi, or animals. Plant galls are abnormal outgrowths of plant tissues, similar to benign tumors or warts in animals. They can be caused by various parasites, from viruses, fungi and bacteria, to other plants, insects and mites. Plant galls are often highly organized structures so that the cause of the gall can often be determined without the actual agent being identified. This applies particularly to some insect and mite plant galls. The study of plant galls is known as cecidology. In human pathology, a gall is a raised sore on the skin, usually caused by chafing or rubbing. Causes of plant galls Insects and mites Insect galls are the highly distinctive plant structures formed by some herbivorous insects as their own microhabitats. They are plant tissue which is controlled by the insect. Galls act as both the habitat a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rosa Arkansana
''Rosa arkansana'', the prairie rose or wild prairie rose, is a species of rose native to a large area of central North America, between the Appalachian and Rocky Mountains from Alberta, Manitoba, and Saskatchewan south to New Mexico, Texas and Indiana. There are two varieties: * ''Rosa arkansana'' var. ''arkansana'' * ''Rosa arkansana'' var. ''suffulta'' (Greene) Cockerell The name ''Rosa arkansana'' comes from the Arkansas River in Colorado. The species' wide distribution and consequent genetic drift has led to an extensive synonymy. It is a perennial subshrub and its native habitats include prairies, roadsides, and ditches. The plant attracts butterflies and birds. The name prairie rose is also sometimes applied to ''Rosa blanda'', also known as the meadow rose or smooth rose, which is also widely spread, but somewhat further to the north. Symbolism Wild rose is the state flower of the U.S. states of Iowa and North Dakota. In Iowa, convention states the species is ''Ros ...

Rosa Acicularis
''Rosa acicularis'' is a flowering plant in the Rosaceae family. It is commonly known as the prickly wild rose, prickly rose, bristly rose, wild rose or Arctic rose. It is a species of wild rose with a Holarctic distribution in northern regions of Asia, Europe, and North America. Description ''Rosa acicularis'' is a deciduous shrub growing 1–3 m tall. The leaves are pinnate, 7–14 cm long, with three to seven leaflets. The leaflets are ovate, with serrate (toothed) margins. The flowers are pink (rarely white), 3.5–5 cm diameter; the hips are red, pear-shaped to ovoid, 10–15 mm diameter. Its native habitats include thickets, stream banks, rocky bluffs, and wooded hillsides. The ploidy of this rose species is variable. Botanical authorities have listed it as tetraploid and hexaploid in North America (subsp. sayi), and octoploid in Eurasia (subsp. acicularis), including China. On the northern Great Plains its populations are generally tetraploid. Hexaploid popu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insects Described In 1890
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Insect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By William Harris Ashmead
In biology, a taxon (back-formation from ''taxonomy''; plural 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. 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 set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
