Bug of the Day!

Xiphydria - Xiphidriid Wood Wasps (Xiphidriidae):

These wasps deposit eggs in dead deciduous wood where their larvae develop as borers. Xiphydriids belong to a paraphyletic grouping of 'primitive' wasps called the Symphyta. They lack the characteristic wasp-waist present in more derived species of Hymenoptera such as Ants, Bees, Hornets, etc.
