Rhopalomyia Conica
''Rhopalomyia'' is a genus of gall midges, insects in the family Cecidomyiidae. There are at least 267 described species in ''Rhopalomyia''. Most species in this genus induce galls on plants in the Asteraceae. This genus has a cosmopolitan distribution. Rhopalomyia was first established by Ewald Heinrich Rübsaamen in 1892.

Rhopalomyia Solidaginis
''Rhopalomyia solidaginis'', the goldenrod bunch gall, is a species of gall midges, insects in the family Cecidomyiidae. The galls of this species have the following host species of goldenrods: ''Solidago altissima'', ''Solidago canadensis'', and ''Solidago rugosa''. They have been found across eastern North America. Gall and biology This species is bivoltine and induces different bud galls in the spring and summer on three different host plants. The spring galls are small and difficult to locate. Galled plants are sometimes stunted. Each gall typically contains only one chamber in the middle of the apical meristem and contains a single larva. Occasionally 2-3 chambers are found in the same gall and may be attached to each other longitudinally. For the summer galls there are white chambers that are similar to those in the spring galls appear in mid-July. Each chamber contains a single larva that faces downwards and is surrounded by a group of short and narrow leaves, whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cecidomyiidae
Cecidomyiidae is a family of diptera, flies known as gall midges or gall gnats. As the name implies, the larvae of most gall midges feed within plant tissue, creating abnormal plant growths called galls. Cecidomyiidae are very fragile small insects usually only in length; many are less than long. They are characterised by hairy wings, unusual in the Order (biology), order Fly, Diptera, and have long Antenna (biology), antennae. Some Cecidomyiids are also known for the strange phenomenon of paedogenesis in which the larval stage reproduces without maturing first. In some species, the daughter larvae consume the mother, while in others, reproduction occurs later on in the egg or pupa. More than 6,650 species and 830 Genus, genera are described worldwide, though this is certainly an underestimate of the actual diversity of this family. A Metabarcoding, DNA metabarcoding study published in 2016 estimated the fauna of Canada alone to be in excess of 16,000 species, hinting at a st ...

Species Description
A species description is a formal scientific description of a newly encountered species, typically articulated through a scientific publication. Its purpose is to provide a clear description of a new species of organism and explain how it differs from species that have been previously described or related species. For a species to be considered valid, a species description must follow established guidelines and naming conventions dictated by relevant nomenclature codes. These include the International Code of Zoological Nomenclature (ICZN) for animals, the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants, and the International Committee on Taxonomy of Viruses (ICTV) for viruses. A species description often includes photographs or other illustrations of type material and information regarding where this material is deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million ... [...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. 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 can be such highly organized structures that their cause can be determined without the actual agent being identified. This applies particularly to insect and mite plant galls. The study of plant galls is known as cecidology. Anatomy Shape and size Galls develop on various plant organs, providing nutrition and shelter to inducing insects. Galls display vast variation in morphology, size, and wall composition. The size of insect galls can range significantly, from approximately two inches in diameter to less than one-sixteenth of an inch. Some galls are so small that they are merely slightly thick ...

Asteraceae
Asteraceae () is a large family (biology), family of flowering plants that consists of over 32,000 known species in over 1,900 genera within the Order (biology), order Asterales. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of Extant taxon, extant species in each family is unknown. The Asteraceae were first described in the year 1740 and given the original name Composita, Compositae. The family is commonly known as the aster, Daisy (flower), daisy, composite, or sunflower family. Most species of Asteraceae are herbaceous plants, and may be Annual plant, annual, Biennial plant, biennial, or Perennial plant, perennial, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions, in a wide variety of habitats. Most occur in Hot desert climate, hot desert and cold or hot Semi-arid climate, semi-desert climates, and they are found on ever ...

Cosmopolitan Distribution
In biogeography, a cosmopolitan distribution is the range of a taxon that extends across most or all of the surface of the Earth, in appropriate habitats; most cosmopolitan species are known to be highly adaptable to a range of climatic and environmental conditions, though this is not always so. Killer whales ( orcas) are among the most well-known cosmopolitan species on the planet, as they maintain several different resident and transient (migratory) populations in every major oceanic body on Earth, from the Arctic Circle to Antarctica and every coastal and open-water region in-between. Such a taxon (usually a species) is said to have a ''cosmopolitan'' distribution, or exhibit cosmopolitanism, as a species; another example, the rock dove (commonly referred to as a ' pigeon'), in addition to having been bred domestically for centuries, now occurs in most urban areas around the world. The extreme opposite of a cosmopolitan species is an endemic (native) species, or one foun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ewald Heinrich Rübsaamen
Ewald Heinrich Rübsaamen (20 May 1857, Haardt – 17 March 1919, Metternich) was a German teacher, artist, and amateur entomologist who studied gall forming insects, especially the gall midges (Cecidomyiidae), and worked on pest control in grapes, most importantly on ''Phylloxera''. Rübsaamen was the second son of Johann Franz and Emilie Mathilde Johanne. His father manufactured precision mechanical instruments for mines. After school at Weidenau, Ewald entered the gymnasium in Siegen and in 1875 went to study mathematics at the Technical College in Karlsruhe. He however gave up studies after four semesters and began to train in art and returned to work as an arts teacher in Hilchenbach. He worked in a primary school in Steinhauserberg from 1878 and then moved to Siegen to head a private school. He also began to study botany and zoology. He took a special interest in gall insects including midges and related nematoceran flies. He described numerous species from collections. In 18 ...

Cecidomyiinae
The Cecidomyiinae, commonly known as gall midges or gall gnats, is the largest subfamily in Cecidomyiidae with over 600 genera and more than 5000 described species. Some of the herbivorous species are inquilines, developing in galls that were initiated by a different midge species. Most species in the genus '' Macrolabis'' and the tribes Trotteriini and Camptoneuromyiini are inquilines, but there are also many inquiline species in genera that are predominantly gall-inducing (such as '' Dasineura'' and '' Lasioptera''). Predatory and parasitoid species comprise about 12% of the Cecidomyiinae. Larvae of these species attack other arthropods - there are known predators of mites, aphids, scale insects, dragonfly eggs, and endoparasitoids of Hemiptera. Most are found in the tribes Aphidoletini and Lestodiplosini. Fungivores make up much of the remainder of the subfamily, indicating the retention of (or reversion to) the ancestral food source.
