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. Subspecies: *''U. gigas gigas'' *''U. gigas taiganus'' ''U. 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.

Urocerus Japonicus
''Urocerus japonicus'', commonly known as the Japanese horntail, is a species of sawfly, native to southeastern Asia. Studies show that the dispersal distance of the female is higher than the male. The fungal species ''Amylostereum laevigatum'' had its first appearance in Japan via this sawfly. Ecology This horntail lays its eggs in the trunk or branches of the Japanese cedar (''Cryptomeria japonica'') or the Japanese cypress (''Chamaecyparis obtusa'') and the larvae feed on the sapwood. When ovipositing, the horntail introduces a symbiont fungus which either provides essential nutrients for the larvae, or which produces enzymes which help decompose the lignin or cellulose in the wood. The staining produced by the fungus reduces the commercial value of the timber. The horntail carries arthrospore An oidium (plural: oidia) is an asexually produced fungal spore that (in contrast to conidia) is presumed not to constitute the main reproductive preoccupation of the fungus at that ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Étienne Louis Geoffroy (October 12, 1725 – August 12, 1810) was a French entomologist and pharmacist. He was born in Paris and died in Soissons. He followed the binomial nomenclature of Carl von Linné and devoted himself mainly to beetle Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota.
