European pine sawfly
European pine sawfly (Neodiprion sertifer) is an insect pest of pines. It is a native of Europe and was first detected in Ohio in 1984.
As the larvae grow, they remain together and feed from the tip of a needle to the base. The larvae feed on older foliage and move from branch to branch as they strip the needles. Trees can be entirely defoliated.
