abstract:The term wood wasp is a colloquial name applied to various unrelated families of Symphyta, whose only shared feature is that the larvae are found in wood. The name is thus applied to "wood wasps" (family Xiphydriidae), "parasitic wood wasps" (family Orussidae), "cedar wood wasps" (Family Anaxyelidae), or, at times, to "horntails" (family Siricidae).
