Tenthredinidae - Tenthredo Temula-001
Tenthredinidae is the largest family of sawflies, with well over 7,500 species worldwide, divided into 430 genera. Larvae are herbivores and typically feed on the foliage of trees and shrubs, with occasional exceptions that are leaf miners, stem borers, or gall makers. The larvae of externally feeding species resemble small caterpillars. As with all hymenopterans, common sawflies undergo complete metamorphosis. The family has no easily seen diagnostic features, though the combination of five to nine antennal flagellomeres plus a clear separation of the first abdominal tergum from the metapleuron can reliably separate them. These sawflies are often black or brown, and 3 to 20 mm long. Like other sawflies, they lack the slender "wasp-waist", or petiole, between the thorax and abdomen, characteristic of many hymenopterans. The mesosoma and the metasoma are instead broadly joined. The Tenthredinidae are also often somewhat dorsoventrally flattened, which will distinguish the ...

Pierre André Latreille
Pierre André Latreille (; 29 November 1762 – 6 February 1833) was a French zoology, zoologist, specialising in arthropods. Having trained as a Roman Catholic priest before the French Revolution, Latreille was imprisoned, and only regained his freedom after recognising a rare beetle species he found in the prison, ''Necrobia ruficollis''. He published his first important work in 1796 (), and was eventually employed by the . His foresighted work on arthropod systematics and Taxonomy (biology), taxonomy gained him respect and accolades, including being asked to write the volume on arthropods for George Cuvier's monumental work, , the only part not by Cuvier himself. Latreille was considered the foremost entomology, entomologist of his time, and was described by one of his pupils as "the prince of entomologists". Biography Early life Pierre André Latreille was born on 29 November 1762 in the town of Brive-la-Gaillarde, Brive, then in the Limousin (province), province of Limo ...

Abdomen
The abdomen (colloquially called the belly, tummy, midriff, tucky or stomach) is the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. The abdomen is the front part of the abdominal segment of the torso. The area occupied by the abdomen is called the abdominal cavity. In arthropods it is the posterior tagma of the body; it follows the thorax or cephalothorax. In humans, the abdomen stretches from the thorax at the thoracic diaphragm to the pelvis at the pelvic brim. The pelvic brim stretches from the lumbosacral joint (the intervertebral disc between L5 and S1) to the pubic symphysis and is the edge of the pelvic inlet. The space above this inlet and under the thoracic diaphragm is termed the abdominal cavity. The boundary of the abdominal cavity is the abdominal wall in the front and the peritoneal surface at the rear. In vertebrates, the abdomen is a large body cavity enclosed by the abdominal muscles, at front and to ...

Pseudosiobla Campbelli
''Pseudosiobla campbelli'' is an extinct species of sawfly in the family Tenthredinidae that is known from early Eocene Ypresian stage lake deposits near the unincorporated community of Horsefly, British Columbia. History and classification The species is known from only the holotype, a single, mostly complete adult female, now deposited in the Geological Survey of Canada collections as specimen number "GSC No. 22689". The shale specimen is from deposits of the " Horsefly shale" along the Horsefly River in the Cariboo District of British Columbia, Canada. The holotype was first studied by Harington Rice of the Geological Survey of Canada. Rice published his 1968 type description for ''P. campbelli'' in the Geological Survey of Canada professional paper number 67-59. The specific name ''campbelli'' was coined in honor of R. B. Campbell who collected the holotype specimen in 1959. ''Pseudosiobla campbelli'' is the smallest species of '' Pseudosiobla'' to be described from ...

Fossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the abs ...

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 ...

Cephoidea
Cephoidea is a small superfamily within the Symphyta, commonly referred to as stem sawflies, containing some 100 species in 10 genera in the living family, Cephidae, plus another 17 genera in the extinct family Sepulcidae. Most species occur in the Northern Hemisphere, especially in Eurasia. The larvae are stem borers in various plants, especially grasses, but sometimes other herbaceous plants, shrubs, or trees. A few are pests of cereal grains (e.g. '' Cephus cinctus'', which attacks wheat). They are exceptionally slender for symphytans, often resembling other types of wasps, and they are the only Symphyta which lack cenchri. They are sometimes postulated to be the sister taxon to the Apocrita, though the Orussidae The Orussidae or the parasitic wood wasps represent a small family of sawflies ("Symphyta"). Currently, about 93 extant and four fossil species are known. They take a key position in phylogenetic analyses of Hymenoptera, because they form the si ... are more commo ...

Metasoma
The metasoma is the posterior part of the body, or tagma, of arthropods whose body is composed of three parts, the other two being the prosoma and the mesosoma. In insects, it contains most of the digestive tract, respiratory system, and circulatory system, and the apical segments are typically modified to form genitalia. In a few of the most primitive insects (the Archaeognatha), the metasomal segments bear small, articulated appendages called "styli", which are often considered to be vestigial. There are also pre-apical appendages in most insect orders, called cerci, which may be multi-segmented and almost resembling a posterior pair of antennae; these may be variously modified, or lost entirely. Otherwise, most adult insects lack appendages on the metasoma, though many larval insects (e.g., caterpillars) have some form of appendages, such as prolegs or, in aquatic insects, gills. In apocritan Hymenoptera (wasps, bees and ants), the metasoma consists of the second abdo ...

Mesosoma
The mesosoma is the middle part of the body, or tagma, of arthropods whose body is composed of three parts, the other two being the prosoma and the metasoma. It bears the legs, and, in the case of winged insects, the wings. In hymenopterans of the suborder Apocrita (wasps, bees and ants), it consists of the three thoracic segments and the first abdominal segment (the propodeum). For historical reasons, in ants it is commonly referred to by the alternative name alitrunk. In scorpions, it is composed of six segments and forms the first part of the abdomen, containing all of the major organs. The first segment contains the sexual organs as well as a pair of vestigial and modified appendages forming a structure called the genital operculum. The second segment bears a pair of featherlike sensory organs known as the pectines; the final four segments each contain a pair of book lungs. The mesosoma is armoured with chitinous plates, on the upper surface by the tergites and on ...
