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.

Trinity County, California
Trinity County is a county located in the northwestern portion of the U.S. state of California. Trinity County is rugged, mountainous, heavily forested, and lies along the Trinity River (for which it is named) within the Salmon and Klamath Mountains. It is also one of three counties in California with no incorporated cities (the other two counties in California with that distinction are Alpine and Mariposa counties). As of the 2020 census, the population was 16,112, making it the fifth least-populous county in California, and the least-populous of California's 27 original counties. The county seat and largest community is Weaverville. History Trinity County has a rich history of Native Americans: Tsnungwe including the South Fork Hupa and tł'oh-mitah-xwe, Chimariko, and Wintu. The county takes its name from the Trinity River, which was in turn named in 1845 by Major Pierson B. Reading, who was under the mistaken impression that the river emptied into Trinidad Bay.

Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists 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. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cynipid 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 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 backside ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galls
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ovipositor
The ovipositor is a tube-like organ used by some animals, especially insects, for the laying of eggs. In insects, an ovipositor consists of a maximum of three pairs of appendages. The details and morphology of the ovipositor vary, but typically its form is adapted to functions such as preparing a place for the egg, transmitting the egg, and then placing it properly. For most insects, the organ is used merely to attach the egg to some surface, but for many parasitic species (primarily in wasps and other Hymenoptera), it is a piercing organ as well. Some ovipositors only retract partly when not in use, and the basal part that sticks out is known as the scape, or more specifically oviscape, the word ''scape'' deriving from the Latin word '' scāpus'', meaning "stalk" or "shaft". In insects Grasshoppers use their ovipositors to force a burrow into the earth to receive the eggs. Cicadas pierce the wood of twigs with their ovipositors to insert the eggs. Sawflies slit t ...

Quercus Vacciniifolia
''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 an ...

Quercus Chrysolepis
''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 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.

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 ...

Insects Of The United States
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. Inse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
