The Anaxyelidae is a wood wasp family within the Symphyta, containing only a single living species, Syntexis libocedrii, (also called the cedar wood wasp or incense-cedar wood wasp), though the family has an extensive Mesozoic fossil record; this species is thus a "living fossil". It has the remarkable behavior of ovipositing only in recently burnt incense-cedar (Calocedrus), redcedar (Thuja) or juniper (Juniperus); the wood is often still smoldering when the wasp is laying its eggs, and the larvae develop in the wood. It occurs from the mountains of central California to southern British Columbia, but is very rarely seen, except by firefighters. Scientific classification or biological classification is a method by which biologists group and categorize species of organisms. ... Animalia redirects here. ...

The NSF is providing substantial financial support for our joint project on the phylogeny of Hymenoptera in the AToL (=Assembling the Tree of Life) framework for the 5 years, from December 2003 until December 2008.

Horntail or wood wasp is the common name for any of the 100 non-social species of the family Siricidae, of the order Hymenoptera, a type of xylophagous sawfly.
This family was until recently the sole living representative of the superfamily Siricoidea, a group well-represented in early Tertiary and Mesozoic times, but the family Anaxyelidae has recently been linked to this group.
The last tergite of the female abdomen has a strong, projecting spike, thus giving the group its common name (the ovipositor is typically longer and also projects posteriorly, but it is not the source of the name).
