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.
