Agrilus cuprescens
Rose Stem Girdler, Bronze Cane Borer
Agrilus cuprescens is a metallic wood-boring beetle in the family Buprestidae, commonly known as the rose stem girdler or bronze cane borer. Native to the Palearctic region, it has been introduced to North America where it has been documented as far west as Washington State. The species is associated with Rosa species and related Rosaceae as larval hosts, with larvae developing in stems and exhibiting girdling behavior. It serves as host for the parasitoid wasp Baryscapus rugglesi.
Nemapogon variatella
Pale Corn Clothes Moth
Nemapogon variatella is a small tineid moth with a wingspan of approximately 12 mm. Native to Europe, it has been introduced to North America where established populations have been documented. The species is associated with fungal and detrital food sources, with larvae recorded feeding on bracket fungi including Coriolus versicolor, Laetiporus sulphureus, and Polyporus squamosus.
Quedius cruentus
orange-tipped rove beetle
Quedius cruentus is a rove beetle in the family Staphylinidae, commonly known as the orange-tipped rove beetle. It is a medium-sized species with distinctive coloration that has been introduced to North America from its native Palearctic range. The species is frequently recorded and has established populations in northeastern North America.
Scolopostethus
dirt-colored seed bugs
Scolopostethus is a genus of dirt-colored seed bugs comprising more than 30 described species in the family Rhyparochromidae. Species occupy diverse habitats including ruderal areas, weedy lawns, and ant-associated environments. Some species are myrmecophilous, living near ant nests through chemical defense strategies rather than chemical mimicry. The genus has a Palearctic origin with at least one species, S. affinis, recently established in North America.
Sepedophilus littoreus
Sepedophilus littoreus is a rove beetle in the family Staphylinidae, originally described from the Palearctic region by Linnaeus in 1758. The species has been introduced to North America, where it is now established across much of Canada and the northeastern and midwestern United States. Historical North American names knoxii and carissimus were synonymized with S. littoreus in a 1976 revision. It belongs to the genus Sepedophilus, which comprises small, agile beetles commonly found in decaying plant matter.
Terellia fuscicornis
Artichoke Fly
Terellia fuscicornis, commonly known as the Artichoke Fly, is a species of tephritid fruit fly first described by Loew in 1844. It is native to the Palearctic region and has been introduced to the United States. The species is associated with artichoke plants, which informs its common name.
