Horntail
Horntails or wood wasps are any of the 150 non-social species of the hymenopteran family Siricidae, a type of xylophagous, 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 Batesian mimicry, mimicry. A typical adult horntail is brown, blue, or black with yellow or red parts, and may often reach up to long. The Tremex columba, 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 ...

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 A larva (; : larvae ) is a distinct juvenile form many animals undergo before metamorphosis into their next life stage.

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] |
Spruce
A spruce is a tree of the genus ''Picea'' ( ), a genus of about 40 species of coniferous evergreen trees in the family Pinaceae, found in the northern temperate and boreal ecosystem, boreal (taiga) regions of the Northern hemisphere. ''Picea'' is the sole genus in the subfamily Piceoideae. Spruces are large trees, from about 20 to 60 m (about 60–200 ft) tall when mature, and have Whorl (botany), whorled branches and cone (geometry), conical form. Spruces can be distinguished from other Genus, genera of the family Pinaceae by their pine needle, needles (leaves), which are four-sided and attached singly to small persistent peg-like structures (pulvini or sterigmata) on the branches, and by their seed cone, cones (without any protruding bracts), which hang downwards after they are pollinated. The needles are shed when 4–10 years old, leaving the branches rough with the retained pegs. In other similar genera, the branches are fairly smooth. Spruce are used as food pla ...

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 ...

Xylophagous
Xylophagy is a term used in ecology to describe the habits of an herbivorous animal whose diet consists primarily (often solely) of wood. The word derives from Greek ξυλοφάγος (''xulophagos'') "eating wood", from (') "wood" and (') "to eat". Animals feeding only on dead wood are called sapro-xylophagous or saproxylic. __TOC__ Xylophagous insects Most such animals are arthropods, primarily insects of various kinds, in which the behavior is quite common, and found in many different orders. It is not uncommon for insects to specialize to various degrees; in some cases, they limit themselves to certain plant groups (a taxonomic specialization), and in others, it is the physical characteristics of the wood itself (e.g., state of decay, hardness, whether the wood is alive or dead, or the choice of heartwood versus sapwood versus bark). Many xylophagous insects have symbiotic protozoa and/or bacteria in their digestive system which assist in the breakdown of cellulose; ...

Hymenoptera
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 reach adulthood. 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 hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xoanon (sawfly)
A xoanon (, ; plural: , from the verb , , to carve or scrape ood was a wooden cult image from Archaic Greece. Classical Greeks associated such cult objects, whether aniconic or effigy, with the legendary Daedalus. Many such cult images were preserved into historical times, though none are known to have survived to the modern day, except as copies in stone or marble. In the 2nd century CE, Pausanias described numerous xoana in his ''Description of Greece'', notably the image of Hera in her temple at Samos. "The statue of the Samian Hera, as Aethilos The name ''Aethilos'' in the available text is thought to be a mis-spelling of ''Aethlios''. says, was a wooden beam at first, but afterwards, when Prokles was ruler, it was humanized in form". In Pausanias' travels he never mentions seeing a xoanon of a "mortal man". Types of xoana Some types of archaic xoana may be reflected in archaic marble versions, such as the pillar-like " Hera of Samos" (Louvre Museum), the flat " Hera ...

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.
