Trichoteras Vacciniifoliae
''Trichoteras vacciniifoliae'', formerly ''Andricus vacciniifoliae'', the golden oak apple wasp'','' is a species of gall-forming hymenopteran. The wasp creates a stem gall on host plants, namely huckleberry oaks and canyon live oaks. ''Andricus vacciniifoliae'' is native to the west coast of North America. Because of their colorful appearance and location on the plant, the galls are often mistaken for fruit. The larval chamber is at the center of the gall, connected to the husk by slender, radiating fibers.

Plumas County
Plumas County () is a county in the Sierra Nevada of the U.S. state of California. As of the 2020 census, the population was 19,790. The county seat is Quincy, and the only incorporated city is Portola. The largest community in the county is East Quincy. The county was named for the Spanish ''Río de las Plumas'' (the Feather River), which flows through it. The county itself is also the namesake of a native moth species, '' Hadena plumasata''. History Before the California Gold Rush of 1849, the indigenous Mountain Maidu were the primary inhabitants of the area now known as Plumas County. The Maidu lived in small settlements along the edges of valleys, subsisting on roots, acorns, grasses, seeds, and occasionally fish and big game. They were decentralized and had no tribal leadership; most bands lived along waterways in and around their own valleys. Areas with high snowfall, including the Mohawk and Sierra valleys, were hunting grounds for game in the warmer months. In ...

Gall
Galls (from the Latin , 'oak-apple') or ''cecidia'' (from the Greek , anything gushing out) are a kind of swelling growth on the external Tissue (biology), 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 Herbivore, herbivorous insects as their own microhabitats. They are plant tissue which is controlled by the insect. Gal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hymenopteran
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Huckleberry Oak
''Quercus vacciniifolia'' (sometimes spelled ''Q. vaccinifolia''), the huckleberry oak, is a member of the ''Protobalanus'' section of genus ''Quercus''. It has evergreen foliage, short styles, very bitter acorns that mature in 18 months, and a woolly acorn shell interior. Description ''Quercus vacciniifolia'' is a shrubby evergreen of the oak family, which grows generally less than tall and spreads horizontally, never becoming a tree. In the field, it is best identified from its clustered terminal buds, which is characteristic of all plants of the genus. Species are more easily identified in the presence of acorns. Acorns of ''Q. vacciniifolia'' mature in 2 years (biennial maturation) after pollination. Flowers and inflorescence characteristics are not used to significant extend in this genera. ''Q. vacciniifolia'' can be easily confused with '' Q. cedrosensis'', which grows in dry chaparrals, such as California-Mexico border south, forests of Baja California a ...

Canyon Live Oak
''Quercus chrysolepis'', commonly termed canyon live oak, canyon oak, golden cup oak or maul oak, is a North American species of evergreen oak that is found in Mexico and in the western United States, notably in the California Coast Ranges. This tree is often found near creeks and drainage swales growing in moist cool microhabitats. Its leaves are a glossy dark green on the upper surface with prominent spines; a further identification arises from the leaves of canyon live oak being geometrically flat. Description ''Quercus chrysolepis'' is an evergreen tree with significant-sized spreading, horizontal branches, and a broad, rounded crown; it attains a height of 6–30 meters (20–100 feet) and often forms as a shrub. The trunk diameter typically ranges from . Exceptionally large specimens are found in the mountains of Southern California, and rank among the largest oaks in North America. The largest known in the San Bernardino Mountains measures high, with a trunk circumfer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trichoteras Coquilletti
''Trichoteras coquilletti'', formerly ''Andricus coquilletti'', also known as the little oak-apple gall wasp, is a fairly common species of cynipid wasp that produces galls on oak trees in North America. This wasp oviposits on the underside of the leaves of huckleberry oaks and canyon live oaks. The larval chamber is at the center of the gall, connected to the husk by slender, radiating fibers. See also * '' Trichoteras vacciniifoliae'' * Oak apple Oak apple or oak gall is the common name for a large, round, vaguely apple-like gall commonly found on many species of oak.

Oak Apple
Oak apple or oak gall is the common name for a large, round, vaguely apple-like gall commonly found on many species of oak. Oak apples range in size from in diameter and are caused by chemicals injected by the larva of certain kinds of gall wasp in the family Cynipidae. The adult female wasp lays single eggs in developing leaf buds. The wasp larvae feed on the gall tissue resulting from their secretions, which modify the oak bud into the gall, a structure that protects the developing larvae until they undergo metamorphosis into adults. Considerable confusion exists in the general literature between the oak apple and the oak marble gall. The oak marble is frequently called the oak apple due to the superficial resemblance and the preponderance of the oak marble gall in the wild. Other galls found on oak trees include the oak artichoke gall and the acorn cup gall, but each of these has its own distinctive form. Some common oak-apple-forming species are the ''Biorhiza pa ...

Cynipidae
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 wasp waist. The first abdominal tergum (the propodeum) is conjoined with the thorax, while the second abdominal segment forms a sort of shaft, the petiole. The petiole connects with the 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. The antennae are straight and consist of two or three segments. In many varieties, the bac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insects Described In 1896
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 eg ... [...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 int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna Of The California Chaparral And Woodlands
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is ''funga''. Flora, fauna, funga and other forms of life are collectively referred to as ''Biota (ecology), biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontology, Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna of Madagascar, Fauna'' comes from the name Fauna (deity), Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan (god), Pan, and ''panis'' is the Greek language, Greek equivalent of fauna. ''Fauna'' is also ...
