Horntail
Horntail or wood wasp are any of the 150 non-social species of the hymenopteran family Siricidae, a type of wood-eating sawfly. The common name "horntail" derives from the stout, spine-like structure at the end of the adult's abdomen, which is used to pierce the host's bark to allow the eggs to be inserted into the wood (the ovipositor is typically longer and also projects posteriorly, but it is not the source of the name). A typical adult horntail is brown, blue, or black with yellow or red parts, and may often reach up to long. The pigeon horntail (''Tremex columba'') can grow up to long (not counting the ovipositor), among the longest of all Hymenoptera. This family was formerly believed to be the sole living representative of the superfamily Siricoidea, a group well represented in Paleogene and Mesozoic times, but the family Anaxyelidae has been linked to this group as well. Siricidae has two subfamilies, Siricinae and Tremecinae. Siricinae infest needle-leaved trees and T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tremex Columba
''Tremex columba'', also known as the pigeon tremex or pigeon horntail, is a species of horntail that is native to eastern and western North America. Appearance and behavior The females are larger than the males, with females growing to 25-30mm in length, and males about 20-25mm. The species can vary in coloration from light brown to dark reddish brown, and sports yellow and black stripes along the abdomen. Both males and females have long projections protruding from their rear, with the females possessing an additional projection in the form of an ovipositor. The females of the species use their ovipositor to deposit their eggs into dead and dying deciduous trees such as beech, elm, maple, and oak, which the larvae burrow inside of and feed upon. They usually deposit between two and seven eggs into the tree. The female will die after this process, and carcasses can sometimes be seen stuck to the bark of host trees.

Urocerus
''Urocerus'' is a genus of horntails in the family Siricidae. There are about eight described species in ''Urocerus''.

Symphyta
Sawflies are the insects of the suborder Symphyta within the order Hymenoptera, alongside ants, bees, and wasps. The common name comes from the saw-like appearance of the ovipositor, which the females use to cut into the plants where they lay their eggs. The name is associated especially with the Tenthredinoidea, by far the largest superfamily in the suborder, with about 7,000 known species; in the entire suborder, there are 8,000 described species in more than 800 genera. Symphyta is paraphyletic, consisting of several basal groups within the order Hymenoptera, each one rooted inside the previous group, ending with the Apocrita which are not sawflies. The primary distinction between sawflies and the Apocrita – the ants, bees, and wasps – is that the adults lack a "wasp waist", and instead have a broad connection between the abdomen and the thorax. Some sawflies are Batesian mimics of wasps and bees, and the ovipositor can be mistaken for a stinger. Sawflies vary in leng ...

Sirex
''Sirex'' is a genus of wasps in the family Siricidae, the horntails or wood wasps. They inject eggs with fungal endosymbionts into wood. The fungus is contained in a mycangium which nourishes it with secretions, and in turn it digests wood for the wasp larva. The genus includes economically important pests; ''S. noctilio'', known simply as the 'Sirex woodwasp' is an invasive species, having spread widely across the world from its original range.Sirex Woodwasp – ''Sirex noctilio''.

Hymenoptera
Hymenoptera is a large order (biology), order of insects, comprising the sawfly, 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 Parasitoid wasp, 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 (biology), 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 language, Ancient Greek wikt:πτερόν, πτερόν (''pteron'') for wing. The Ancient Greek wikt:ὑμήν, ὑμήν (''hymen'') for membrane provides a plausible etymology for the term bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urocerus Gigas
''Urocerus gigas'' (giant woodwasp, banded horntail, greater horntail) is a species of sawfly native to the Palearctic realm and North Africa. Adults are usually between in length.

Siricoidea
The superfamily Siricoidea is an archaic group of the order Hymenoptera, consisting of six families (four extinct) of xylophagous sawflies. The group is well represented in early Tertiary and Mesozoic times, but a number of living taxa remain, including the family Anaxyelidae, which has recently been linked to this group (it was previously placed in the Xyeloidea). The female ovipositor is typically long and projects posteriorly, and is used to drill into wood. Families These six families belong to the superfamily Siricoidea: * Siricidae (horntails) * Xiphydriidae Xiphydriidae are a family of wood wasps that includes around 150 species. They are located all over the world including North and South America, Australia, Europe, and others. Xiphydriidae larvae are wood borers in dead trees or branches of a ran ...

Wasp
A wasp is any insect of the narrow-waisted suborder Apocrita of the order Hymenoptera which is neither a bee nor an ant; this excludes the broad-waisted sawflies (Symphyta), which look somewhat like wasps, but are in a separate suborder. The wasps do not constitute a clade, a complete natural group with a single ancestor, as bees and ants are deeply nested within the wasps, having evolved from wasp ancestors. Wasps that are members of the clade Aculeata can Stinger, sting their prey. The most commonly known wasps, such as yellowjackets and hornets, are in the family Vespidae and are Eusociality, eusocial, living together in a nest with an egg-laying queen and non-reproducing workers. Eusociality is favoured by the unusual haplodiploid system of sex-determination system, sex determination in Hymenoptera, as it makes sisters exceptionally closely related to each other. However, the majority of wasp species are solitary, with each adult female living and breeding independently ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xeris
''Xeris'' is a genus of horntails found in North America and Eurasia. Achille Costa circumscribed the genus in 1894. Synonyms In 1987, Malkiat S. Saini and Devinder Singh circumscribed a new genus, ''Neoxeris'' upon their description of a new species, which they called ''Neoxeris melanocephala''. In 2012, ''N. melanocephala'' was transferred to ''Xeris'', making ''Neoxeris'' a junior synonym. ''X. melanocephalus'' was later synonymized with ''X. himalayensis''. Description Characteristic features of ''Xeris'' compared to other genera of Siricidae genera include: a hind wing with which lacks a cell cup, a small vertical ridge behind the eye, and a metatibial spur. Distribution ''Xeris'' species are found in North America and Eurasia. In North America, they're found from the boreal forests in Alaska and Canada south through Chiapas in southern Mexico. They are found in temperate and boreal regions of Eurasia as well as mountains of southern Eurasia including Morocco, India, China ...

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 the ...
