Alphabetical List of Critters - European Pine Sawfly
The European Pine Sawfly, Neodiprion sertifer (Geoffroy), is an insect that infests pines and is originally from Europe, as its name suggests. The damaging stage is the caterpillar-like* larval stage (see photo). It was accidentally introduced to the U.S. and is now a very common resident of pines in landscapes, Christmas tree farms, and ornamental nurseries. It is common from southwestern Ontario through New England and west as far as Iowa.
*Sawfly larvae look like caterpillars but they are actually the larvae of primitive wasp-like insects.
