Moved
It basically rotates the apical segment of the metasoma such that the intersegmental membranes enclose the ovipositor and exert pressure that helps to push it into the wood as the valvulae alternatively move during the drilling process to reach the larva of the pigeon Tremex, the host that has developed in the wood.

Moved from Ichneumon Wasps.
