The diprionid sawflies, the group to which Neodiprion swainei Middleton belongs, have been known to science for many years. Linnaeus listed two species in the Tenth Edition of his Systema Naturae published in 1758, and Ratzeburg in 1844 devoted thirty-four pages of his text to a discussion of the fifteen species he recognized. Thus long known as serious pests of the Pinaceae in Europe, the diprionids have attracted increasing attention in North America since the early decades of the twentieth century, coincident with the increased planting of large areas to pines and the rapid increase in exploitation of virgin forests.
