Xeris Spectrum
''Xeris spectrum'' is a kind of horntail or wood wasp, that lives in coniferous forests. It is large wasp with a powerful ovipositor in females. Unlike other Siricid Wood wasps, ''Xeris spectrum ''does not have symbiotic fungi to aid its larvae as they burrow in the wood of fir and other conifer trees making it unique in the Siricidae. It is widespread and is found in large parts of Europe, Asia, Africa and North America. Appearance The body of ''Xeris spectrum'' is cylindrical. The head is broadest behind the eyes, and antennae are thread-shaped. Both sexes are equal in length, between . The body is black or dark brown and shiny with white spots behind the eyes and on the sides of the prothorax. ''Xeris spectrums legs are orange-red. Males have brown rings around the leg. The body of the larvae is cylindrical and slightly flattened and is up to long. The pupa is in length. The antennae of the pupa extend beyond the wings at the level of the eighth segment.

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]   |
