Family PAMPHILIIDAE 



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, dor- 

 soventrally flattened insects, and are sometimes common around the flowers of their host plants 

 in the spring.
