Orussus abietinus (Hymenoptera: Orussidae) - a parasitic wood wasp !

Description:

The Orussoidea, parasitic wood wasps, have retained a relatively ancestral form of ectoparasitism ofbuprestid beetles and siricid woodwasps... Little is known of the mode of action of the venom, if any, but late-instar larvae appear to feed on or in the host after it is dead.The phylogenetic relation of Orussidae within the order of hymenoptera seems to be: [Siricoidea + (Orussoidea + Apocrita)].source: J.
