Filacus pluricinctellus
Filacus pluricinctellus is a of in the Tenthredinidae. The Filacus is a small group within this family, and F. pluricinctellus is one of the few described species. It is known from a limited number of observations, primarily in western North America. As with other sawflies, the larvae are likely herbivorous, though specific plants remain undocumented.
