Diprion similis: Diprion similis is a species of sawfly in the family Diprionidae.

It is also known as the white pine sawfly because of its preference for feeding on the white pine, but this name is confusing because another sawfly, "Neodiprion pinetum", whose larvae also feed on this tree, is itself known as the "white pine sawfly".
