Though several species of parasitoids are associated with Siricidae on conifers, they belong to only a few hymenopteran families. Few parasitoid species have been associated with species of Xeris (Spradbery and Kirk 1978, and collections studied here). It is likely that more species of the known parasitoids of other siricid genera associated with conifers also attack larvae of Xeris.
