Journal of Hymenoptera Research 39: 17–31. doi: 10.3897/JHR.39.7907 Abstract A diverse sawfly fauna of 176 species in 66 genera in 10 families occurred in three parks in the George Washington Memorial Parkway – Dyke Marsh Wildlife Preserve (DMWP), Great Falls Park (GFP), and Turkey Run Park (TRP). Adult sawflies flew from early March through mid-November. They included the rarely-collected Kerita fidala Ross, a leafminer of Mertensia virginica (L.) Pers. ex Link (Boraginaceae) and an unidentifiedCaliroa sp. which consumes Staphylea trifolia L. (Staphyleaceae). Nine of the collected species are alien ones in North America.
