Scotch broom (Sarothamnus scoparius (L) Wimmer) and its insect fauna introduced into the Pacific Northwest of America.
Since its introduction from Europe to the Pacific coast of North America, Scotch broom has spread and has become a weed. The main broom sites in California and British Columbia were visited and the insect fauna was examined. Some of the introduced insect species that were found are new records. F.s.-D.B.
