Guides
Acmaeodera perlanosa
Acmaeodera perlanosa is a species of metallic wood-boring beetle in the family Buprestidae, described by Timberlake in 1939. The species belongs to a large genus of flower-visiting buprestids found primarily in western North America. Based on field observations, adults have been collected from flowers of Eriodictyon angustifolium in pinyon/juniper woodland habitats of southwestern Utah.
Ethmia arctostaphylella
Ethmia arctostaphylella is a small moth in the family Ethmiidae (formerly Depressariidae), distributed across the western United States and Mexico. Adults have forewings measuring 8.4–11.7 mm, with a distinctive color pattern of dark gray on the costal half and whitish gray on the dorsal half, separated by a longitudinal line and marked with black spots. The species exhibits an extended flight period from February to October. Larvae are specialized feeders on Eriodictyon species (yerba santa), a relationship that shapes its geographic distribution.
Phytomyza eriodictyi
Phytomyza eriodictyi is a leaf-mining fly in the family Agromyzidae, described by Spencer in 1981. As a member of the genus Phytomyza, it likely shares the characteristic larval habit of feeding within leaf tissue, creating distinctive serpentine mines. The specific epithet 'eriodictyi' suggests an association with Eriodictyon, a genus of flowering plants in the waterleaf family (Hydrophyllaceae) native to western North America.
Pseudomasaris micheneri
Pseudomasaris micheneri is a pollen wasp in the subfamily Masarinae, described by Bohart in 1963. Like other members of its genus, it is a solitary wasp that constructs mud nests and provisions cells with pollen and nectar rather than paralyzed prey. The species belongs to a group of wasps that exhibit oligolectic pollination relationships, primarily visiting flowers in the genera Penstemon, Phacelia, and Eriodictyon. Males are known to exhibit hilltopping behavior, perching at elevated sites to await females.
Pseudopsallus angularis
yerba santa plant bug
Pseudopsallus angularis is a species of plant bug in the family Miridae. It is distributed across western North America from the southwestern United States into northwestern Mexico, with records from California, Nevada, Oregon, Arizona, and Baja California. The species is associated with yerba santa (Eriodictyon species) and related host plants.
