Xiphydria is a genus of wood wasps belonging to the family Xiphydriidae. [1]
This genus is Holarctic, being found in Europe, Asia and North America. [1]
In Xiphydria, the head has mandibles each with four teeth, 5-segmented maxillary palps, a clypeus with a medial tooth-like projection and antennae with about 20 segments. The pronotum is strongly constricted in dorsal view and the propleuron is long in lateral view (this means the head is positioned on a relatively long "neck"). The hind wing has only two closed cells. [2]
Larvae are white and grub-like. They resemble larvae of Siricidae, another wood-boring group of sawflies. [2]
Female Xiphydria oviposit into diseased or dead wood, often branches that have fallen or are about to fall (widowmakers). During oviposition, they also infect the wood with a symbiotic fungus that starts decomposing the wood. Eggs hatch into larvae that bore galleries into wood parallel to the grain. As larvae feed, they pack frass (waste) behind their bodies. At maturity, larvae become prepupae which switch direction so the gallery runs towards the outside of the branch (this is to reduce the amount of wood that needs to be chewed through later). The next step is pupation. Once that is complete, adult wasps emerge, leaving behind emergence holes ~3 mm wide in the wood. This genus is univoltine, meaning there is one generation per year. [2]
They attack a range of different broadleaf trees: Acer (maple), Betula (birch), Ulmus (elm), Carya (hickory), Populus (cottonwood), Salix (willow), Alnus (alder), Platanus (sycamore, plane), Rhus (sumac), Fagus (beech), Fraxinus (ash), Tilia (basswood), Ostrya (hophornbeam), Crataegus (hawthorn), Carpinus (hornbeam), Prunus (cherry, plum), and Quercus (oak). [2]
Xiphydriidae may occur in firewood or raw woodworking materials. While usually of little economic importance, X. longicallis can cause economic damage to oak wood. [2]
The following species are recognised in the genus Xiphydria: [1]
The Tachinidae are a large and variable family of true flies within the insect order Diptera, with more than 8,200 known species and many more to be discovered. Over 1,300 species have been described in North America alone. Insects in this family commonly are called tachinid flies or simply tachinids. As far as is known, they all are protelean parasitoids, or occasionally parasites, of arthropods, usually other insects. The family is known from many habitats in all zoogeographical regions and is especially diverse in South America.
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 longhorn beetles (Cerambycidae), also known as long-horned or longicorns, are a large family of beetles, with over 35,000 species described.
Gall wasps, also traditionally calledgallflies, 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 are known worldwide, with about 360 species of 36 different genera in Europe and some 800 species in North America.
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. A typical adult horntail is brown, blue, or black with yellow or red parts, and may often reach up to 4 cm (1.6 in) long. The pigeon horntail can grow up to 5 cm (2.0 in) long, among the longest of all Hymenoptera.
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 range of trees. They are characterized as having long and skinny necks with dome-shaped heads. The oldest fossils of the group are from the mid Cretaceous.
The family Oedemeridae is a cosmopolitan group of beetles commonly known as false blister beetles, though some recent authors have coined the name pollen-feeding beetles. There are some 100 genera and 1,500 species in the family, mostly associated with rotting wood as larvae, though adults are quite common on flowers. The family was erected by Pierre André Latreille in 1810.
Ripiphoridae is a cosmopolitan family of some 450 described species of beetles sometimes called "wedge-shaped beetles". Ripiphoridae are unusual among beetle families in that many species are hypermetamorphic parasitoids, an attribute that they share with the Meloidae. Members of the family differ in their choice of hosts, but most attack various species of bees or wasps, while some others attack cockroaches or beetles. Many species of Ripiphoridae have abbreviated elytra, and flabellate or pectinate antennae.
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 sister taxon of the megadiverse apocritan wasps, and the common ancestor of Orussidae + Apocrita evolved parasitism for the first time in course of the evolution of the Hymenoptera. They are also the only sawflies with carnivorous larvae.
The Xyelidae are a comparatively species-poor family of sawflies, comprising about 80 extant species in five genera worldwide, and is the only family in the superfamily Xyeloidea. The fossil record of the family is extensive, comprising more than 120 species and including the oldest fossil Hymenoptera species dating back to the Triassic, between 245 and 208 million years ago. Xyelidae are to be regarded as living fossils since they represent one of the oldest lineages of insects and include still extant forms.
Pamphiliidae is a small wasp family within Symphyta, containing some 200 species from the temperate regions of North America and Eurasia. The larvae feed on plants, using silk to build webs or tents, or to roll leaves into tubes in which they feed, thus earning them the common names leaf-rolling sawflies or web-spinning sawflies. Some species are gregarious and the larvae live in large groups. Fossils of Pamphiliidae have been dated to the Jurassic period.
The Tenthredinoidea are the dominant superfamily of sawflies within the Symphyta, containing some 8,400 species worldwide, primarily in the family Tenthredinidae. All known larvae are phytophagous, and a number are considered pests.
Acantholyda is a genus of sawflies.
Pamphilius is a genus of leaf-rolling sawflies within the Symphyta belonging to the family Pamphiliidae.
Tenthredo is a genus of sawflies with more than 700 species of the family Tenthredinidae, subfamily Tenthredininae. It is of Holarctic distribution.
Cephidae is a family of stem sawflies in the order Hymenoptera. There are about 27 genera and more than 160 described species in Cephidae.
Dahlbominus fuscipennis, the sawfly parasitic wasp, is a species of chalcid wasp from the family Eulophidae which parasitizes the European pine sawfly Neodiprion sertifer, among other hosts. It is the only species in the genus Dahlbominus.
Heteroperreyia hubrichi is a South American sawfly that feeds on plants of the genus Schinus.
Megischus is a genus of crown-wasps in the parasitoid family Stephanidae. There are over 90 species globally distributed throughout the Neotropical, Palearctic, Afrotropical, Oriental, Australasian, and Oceanian zoogeographical regions.
Xiphydria prolongata, commonly known as willow wood wasp or red-belted necked wood wasp, is a species of sawfly in the family Xiphydriidae. It is native to Europe and has been introduced to North America.
