Interpretive Summary: Seed bugs are serious nuisance pests. They may invade houses and other buildings in large numbers, causing anxiety among homeowners and creating costly control expenses for commercial establishments. Two invasive Old World seed bugs are recorded for the first time in North America, one from California and northern Utah and the other from Oregon and Washington. A diagnosis, description, photograph of the adult, summary of the literature, and notes on the biology and habitat for each seed bug are given to separate these invasive bugs from native North American species. This information will be important to state, federal, and extension workers involved in identifying and tracking recently established exotic insects to determine their pest status and environmental impact in the United States.

Technical Abstract: Two invasive Palearctic rhyparochromids (Lygaeoidea: Rhyparochromidae) are recorded for the first time in North America. Raglius alboacuminatus Goeze is reported from California and northern Utah and Rhyparochromus vulgaris (Schilling) from Oregon and Washington. Although not considered major agricultural pests, these invasive bugs have become serious nuisance pests, invading homes and commercial establishments in large numbers. Provided for each are a summary of the literature, notes on the biology and habitat, diagnosis, description, and photographs of the adult to help separate these nonindigenous bugs from other North American Rhyparochromidae.
