       Eriocampa is a genus of sawfly that is still alive today,‭ ‬but is also known from several extinct species that seem to have been common in North America during the Eocene,‭ ‬though one species,‭ ‬E.‭ ‬oligocenica,‭ ‬is recorded as being alive during the‭ ‬Oligocene of France.‭ ‬At the time of writing there are eight recorded extinct species of Eriocampa‭; ‬E.‭ ‬bruesi,‭ ‬E.‭ ‬celata,‭ ‬E.‭ ‬oligocenica,‭ ‬E.‭ ‬pristina,‭ ‬E.‭ ‬scudderi,‭ ‬E.‭ ‬synthetica,‭ ‬E.‭ ‬tulameenensis and E.‭ ‬wheeleri.‭ ‬Out of all these,‭ ‬E.‭ ‬tulameenensis from the Eocene of Canada is recorded as being the largest.‭ ‬However the incomplete preservation of the E.‭ ‬tulameenensis type specimen makes a precise measurement hard to establish other than it was larger than other known extinct species.
