Aceria paracalifornica
California Sagebrush Gall Mite
Aceria paracalifornica, commonly known as the California Sagebrush Gall Mite, is a species of eriophyid mite in the family Eriophyidae. As a member of the superfamily Eriophyoidea, it is a worm-like, four-legged mite that parasitizes plants. The genus Aceria includes numerous species that cause distinctive plant deformities including galls, witches' brooms, and leaf distortions. The specific epithet "paracalifornica" suggests a close relationship to or similarity with A. californica, a species associated with California sagebrush (Artemisia californica). Eriophyid mites in this genus are highly host-specific, typically specializing on a single plant species or genus.
Aseptis susquesa
Aseptis susquesa is a noctuid moth described by John Bernhardt Smith in 1908. It occurs in the southwestern United States and northwestern Mexico, inhabiting rocky desert and mountain-desert transition zones. Adults fly in spring, and larvae feed on specific desert shrubs.
Calycomyza artemisivora
Calycomyza artemisivora is a leaf-mining fly species in the family Agromyzidae, described in 2018. The species name refers to its association with Artemisia host plants. As a member of Calycomyza, it is part of a genus containing numerous leaf-miner species that create distinctive feeding patterns within plant tissues.
Chlorita
Chlorita is a genus of leafhoppers in the family Cicadellidae, subfamily Typhlocybinae. The genus was established by Fieber in 1872. Species occur in Europe, with documented records from Denmark, Norway, Sweden, and southern Italy. Some species exhibit strict host plant associations, including monophagy on Artemisia campestris subsp. variabilis.
Connatichela artemisiae
Connatichela artemisiae is a monotypic weevil species endemic to the Yukon Territory, Canada, and the sole member of its genus. The species was described in 1984 and represents a distinctive lineage within the subfamily Entiminae, characterized by unique tarsal claw morphology. Fossil evidence indicates a broader Pleistocene distribution across Beringia, with modern restriction to the Yukon likely reflecting post-glacial habitat loss. Adults have been documented in association with small Artemisia species.
Eutreta
Eutreta is a genus of fruit flies (family Tephritidae) established by Loew in 1873. The genus comprises 36 species distributed across three subgenera: Eutreta, Metatephritis, and Setosigena. Species in this genus are known for inducing galls on host plants, with documented associations to Asteraceae and Verbenaceae families. At least one species, Eutreta xanthochaeta, has been introduced to multiple regions for attempted biological control of invasive weeds.
Hypochlora alba
Cudweed Grasshopper, Mugwort Grasshopper, Sage Grasshopper
Hypochlora alba is a short-winged, monophagous grasshopper in the family Acrididae. It is the only known grasshopper species capable of surviving on cudweed sagewort (Artemisia ludoviciana), a plant whose pubescent leaves deter other grasshoppers. The species is found in grasslands east of the Rocky Mountains, where its distribution closely tracks that of its host plant. It is primarily flightless, with females occasionally producing long-winged forms. The species has been studied as a model for specialist herbivore-plant interactions and phytophilous behavior.
Melanoplus bowditchi
Sagebrush Grasshopper
Melanoplus bowditchi, commonly known as the sagebrush grasshopper, is a medium-sized spurthroated grasshopper in the subfamily Melanoplinae. It is widely distributed across western North American grasslands where sagebrush is present. The species exhibits strong host plant specificity, feeding almost exclusively on sagebrush species, particularly silver sagebrush (Artemisia cana) and sand sagebrush (A. filifolia). Despite its potential to damage valuable forage plants, populations remain at low densities and significant economic impact has not been documented.
Rhopalomyia pomum
Sponge Gall Midge
Rhopalomyia pomum, commonly known as the sponge gall midge, is a gall-forming insect in the family Cecidomyiidae. The species induces distinctive leaf galls on Great Basin sagebrush (Artemisia tridentata). It was described by Gagné in 1975 and is recognized as a valid species in current taxonomic databases.
Schinia acutilinea
Acute-lined Flower Moth, Angled Gem
Schinia acutilinea is a small noctuid moth found in arid western North America. Adults have a wingspan of 25–27 mm and are active in August. The species was described by Augustus Radcliffe Grote in 1878 and was synonymized with Schinia accessa by David F. Hardwick in 1996, though subsequent research by Michael G. Pogue suggests this lumped multiple distinct species.
Trirhabda pilosa
Trirhabda pilosa is a skeletonizing leaf beetle in the family Chrysomelidae, native to North America. The species is a specialist herbivore of sagebrush (Artemisia spp.) and has been extensively used in ecological research as a model organism to study plant-to-plant communication and induced plant resistance. Larvae demonstrate consistent behavioral avoidance of leaves exposed to damage cues, making them valuable for rapid bioassays of plant defensive responses.
