Pamphiliidae (sometimes incorrectly spelled Pamphilidae) is a small wasp family within Symphyta, containing some 200 species from the temperate regions of North America and Eurasia. The larvae feed on plants (often conifers), using silk to either build webs or tents, or to roll leaves into tubes, in which they feed, thus earning them the common names leaf-rolling sawflies or web-spinning sawflies. They are distinguished from the closely related Megalodontesidae by their simple, filiform antennae.
