Brachylomia
Minor Shoulder-knot (B. viminalis)
Brachylomia is a genus of small noctuid moths in the tribe Xylenini, containing approximately 17 described species. The genus occurs across the Holarctic region, with species distributed in North America, Europe, and Asia. Brachylomia viminalis, the Minor Shoulder-knot, is the best-known species and serves as the primary reference for understanding the genus. Most species are associated with damp habitats and willow-dominated vegetation.
Caloptilia palustriella
Caloptilia palustriella is a leaf-mining moth in the family Gracillariidae, known only from California. The species was described by Braun in 1910. Its larvae feed on willows (Salix species), creating mines within the leaves.
Colias gigantea
Giant Sulphur, Giant Northern Sulfur
Colias gigantea, the giant sulphur, is a medium-sized butterfly in the family Pieridae found across northern North America. It inhabits tundra and willow bog habitats from Alaska eastward across Canada to the Atlantic coast, with disjunct populations in the northern Rocky Mountains. Adults are active from June through early August, with larvae feeding exclusively on willow species (Salix spp.) and adults taking flower nectar.
Digrammia gnophosaria
Hollow-spotted Angle
Digrammia gnophosaria, commonly known as the hollow-spotted angle, is a species of geometrid moth native to central and eastern North America. The species was first described by Guenée in 1858 and was originally placed in the genus Tephrina before being transferred to Digrammia. Larvae have been documented feeding on Salix species, including Salix babylonica.
Limenitis archippus lahontani
Nevada Viceroy
Limenitis archippus lahontani is a subspecies of the Viceroy butterfly, commonly known as the Nevada Viceroy. It is part of a well-known mimicry complex with the Monarch butterfly (Danaus plexippus), though recent research suggests the Viceroy itself may also be chemically protected rather than a pure Batesian mimic. This subspecies is found in western North America, particularly in the Great Basin region.
