The Pamphilioidea are a small superfamily within the Symphyta (the sawflies), containing some 250 living species restricted to the temperate regions of Eurasia and North America. These hymenopterans share the distinctive feature of a very large, almost prognathous head, which is widest ventrally.
The superfamily contains two extant families. The Pamphiliidae are the leaf-rolling or web-spinning sawflies such as Acantholyda, Neurotoma, and Pamphilius whose larvae eat plants such as conifers; the adults have simple filiform antennae. The Megalodontesidae include genera such as Megalodontes and several fossil groups. Their larvae eat herbaceous plants, while the adults have serrate or pectinate antennae.[2]
