Аннотация:The pine bark adelgid, Pineus strobi (Hartig, 1839) (Hempitera: Adelgidae), is native to eastern North America and is found throughout the natural range of its main host species, eastern white pine, Pinus strobus L. (Pinaceae), which stretches from the Atlantic coast, west to Ontario and Minnesota (Drooz 1985). For the first time, we confirmed the presence of P. strobi west of this range in Washington, Colorado, and Saskatchewan by identification of contemporary samples using morphology and DNA barcodes. We also include information from existing slide-mounted specimens of P. strobi putatively originating from Oregon that are deposited in the United States National Museum of Natural History (NMNH) Entomology Collection. To our knowledge, this is the first published report of this species in western North America.
