Pamphilioidea

The Megalodontesidae (until recently spelled Megalodontidae, a name already in use for a family of fossil molluscs) are a small family of sawflies, containing a single living genus, Megalodontes, with some 40 species restricted to the temperate regions of Eurasia. Larvae of Megalodontesidae feed on herbaceous plants. They are distinguished from the closely related Pamphiliidae by their serrate or pectinate antennae.
