Sawflies of Oregon - Nature Photography, up close, by Phil Huntley-Franck

PURPOSE:
This image gallery has been created to assist visitors in the identification of Sawflies, Horntails, and Wood Wasps. First, Sawflies are not flies. They are most closely related to Bees and Wasps. For the most part, I haven't run across any Horntails or Wood Wasps, that I know of, but I have encountered a number of Sawflies. From what I've gleened, Sawflies can be told apart from most other Hymenoptera by the broad (thick-waisted) connection between the abdomen and the thorax, and by their larvae, which look like little caterpillers and slugs, sort of.

PHOTOGRAPHIC LOCATIONS AND DATES:
Currently, the Sawfly identification on this page is specific to all Sawflies that show up in and around my yard. These Sawflies, however, are also found in many other parts of the country.

Unless otherwise noted, all images were taken in Northern Douglas County, Oregon.

The date each photograph was taken appears under each thumbnail image. The sex of each specimen, if known, is also indicated under each thumbnail.
