What's That Bug? says :
Dear Cicada Lover,
We agree with you that this appears like it might be a European Spruce Sawfly larva as pictured on BugGuide. Have you any other images? It would be great if you had an image where we are able to count the prolegs. According to Natural Resources Canada: “Native to Europe, the European spruce sawfly was first reported in Canada in 1922 and in the United States in 1929, but did not really attract the attention of foresters until 1930, when it caused severe damage to spruce stands in Quebec’s Gaspé peninsula. The infestation spread rapidly throughout northeastern North America. The discovery of this infestation led to the development of a national forest insect inventory network consisting of the states in the northeastern U.S. Sawfly populations began to decline in 1938 with the emergence of a viral disease that affects the larvae, returning to endemic levels in 1945, where it has since remained throughout Canada. Its current Canadian range extends from the Atlantic provinces to Manitoba.” Tennessee is further south than any reported BugGuide sightings. Please let us know if you learn anything new from the BugGuide posting.
