    Pamphiliidae: Brief Summary
    provided by wikipedia

    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.

    Brief Summary
    provided by Catalog of Hymenoptera in America North of Mexico
    Commonly called webspinning sawflies, the larvae live solitarily or socially in a web or in a rolled leaf held by silk. The subfamily Cephalciinae is associated with conifers, and the subfamily Pamphiliinae is associated with deciduous trees or shrubs. Adults of most species are large, dorsoventrally flattened insects, and are sometimes common around the flowers of their host plants in the spring.
