Biosystematics and morphology of Symphyta. II. Biology of gall-making nematine sawflies in the California region

a gall, similar to the one made by P. proxima, is made by a species on the native S. lasiandra in the Sierra Nevada and adjacent ranges at elevations of 1660-2200 m, and it is unlikely that it will prove to be P. proxima.
