Xiphydria
wood wasps, xiphydriid wood wasps
Xiphydria is a genus of wood wasps in the family Xiphydriidae, distributed across the Holarctic region including Europe, Asia, and North America. Adults are characterized by a distinctive elongated 'neck' formed by the long propleuron, antennae with approximately 20 segments, and mandibles with four teeth. Females oviposit into diseased or dead wood of broadleaf trees and vector symbiotic fungi that decompose wood for larval consumption. The genus is univoltine with one generation per year. While generally of minor economic importance, some species can damage oak and other hardwoods.
