Limneria H. Adams & A. Adams 1851

This is a large genus. As presently defined in the structural sense, it appears to include species from all zoogeographic regions, but by far the greatest number of species occur in the Holarctic Region. From our knowledge of the habits of a considerable number of the species occurring in the Holarctic Region there has developed the supposition that parasitism of sawfly larvae clearly distinquishes Olesicampe from Hyposoter (parasites of Lepidoptera larvae). Structural differentiatiton of the two genera is rather arbitrary, however, particularly when one looks at the world fauna, in which case the differentiation of Olesicampe from Lemophagus also appears arbitrary. Although it seems certain that some of the species currently placed in Olesicampe will prove not to be parasites of sawflies, it appears equally as certain that nearly all of the Nearctic and Palearctic species of Olesicampe are parasites of sawflies. In all cases known to me, Olesicampe species kill the host after it has spun its cocoon and emerge as adults from the host cocoon.
