Siricidae
Horntails or wood wasps 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 present in both sexes. The ovipositor in females is typically longer and also projects posteriorly, but it is not the source of the name. Though they are not wasps, they are sometimes called wood wasps as the appearance of some species resembles one due to mimicry. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sirex Noctilio
''Sirex noctilio'', known as the Midnight woodwasp, European woodwasp, European horntail woodwasp, or sirex woodwasp, is a species of horntail, woodwasp, native to Europe, Asia, and northern Africa.New York State Department of Environmental Conservation, Copyright © 2011. Sirex Woodwasp – ''Sirex noctilio''. http://www.dec.ny.gov/animals/7248.html Adults vary in length from . This woodwasp is an invasive species in many parts of the world, including Australia, New Zealand, North America, South America, and South Africa, where it has become a significant economic pest of pine trees. The wasp can attack a wide variety of pine species, although some species seem to be more susceptible than others, and stressed trees often are attacked. During oviposition, the female wasp lays two eggs with or without a mucoid connective tissue, mucoid substance and a symbiosis, symbiotic fungus for the larvae to feed on once they hatch. The mucoid substance is toxic to trees and aids in tree d ... [...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 Chiapas, officially the Free and Sovereign State of Chiapas, is one of the states that make up the Political divisions of Mexico, 32 federal entiti ...

Afrotremex
''Afrotremex'' is a rare genus within the family Siricidae found in central and west Africa. The genus is thought to reside in tree canopies. Adults can be distinguished from closely related genera by three clearly outlined longitudinal bands of sculpture on the mesonotum, and by the clubbed seta In biology, setae (; seta ; ) are any of a number of different bristle- or hair-like structures on living organisms. Animal setae Protostomes Depending partly on their form and function, protostome setae may be called macrotrichia, chaetae, ...e on the clypeus, frons, and behind the eyes.

Sawfly
Sawflies are wasp-like insects that are in 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. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sirex
''Sirex'' is a genus of sawfly in the family horntail, Siricidae, the horntails or wood wasps. Their bodies are black with a dark blue or green metallic reflection with some species having reddish-brown portions. They inject eggs with fungal endosymbionts into wood. The larvae of ''Sirex'' are unable to digest the wood on their own and rely on the fungus for nutrition, either eating the fungus or wood partially digested by the fungus. Female ''Sirex'' have a mycangium which is used to carry Oidium (spore), arthrospores of the fungus. 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.Hurley, B.

Urocerus Gigas
''Urocerus gigas'', the giant woodwasp, banded horntail, or greater horntail, is a species of sawfly native to the Palearctic realm and North Africa but also reside in North America and Kelty since 2004. Though they are not wasps, their appearance resembles one due to mimicry. Adults are usually between in length. Subspecies: *''Urocerus gigas gigas'' *''Urocerus gigas taiganus'' ''Urocerus gigas'' is a wood-boring insect that attacks softwoods of freshly felled logs/unhealthy trees. The species lives in discrete tunnels, frequently filled with hard-packed coarse fibrous frass, hard to dig out from tunnels. The tunnels are large, round and discrete, between in diameter. Both sexes have a chitinous spike emerging from the abdomen, derived from the last segment, which is found in all Horntail, woodwasps. However, unlike in true Wasp, wasps, the projection is harmless and cannot sting. The second, longer and lower projection in females only is the ovipositor. The ovipositor ha ...

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 its own superfamily, Anaxyeloidea).Gao J, Engel MS, Shih C, Ren D, Gao T (2021) A new genus of anaxyelid wood wasps from the mid-Cretaceous and the phylogeny of Anaxyelidae (Hymenoptera).
