Ablautus
Prospectors
Ablautus is a genus of small robber flies (family Asilidae) containing approximately 14 described species. Adults measure 6–7 millimeters and inhabit arid regions of western and southwestern North America, particularly sandy areas within sagebrush communities. The genus exhibits notable mimicry relationships, with Ablautus mimus known to mimic Lestomyia sabulonum. Species were described primarily by J. Wilcox during 1935–1966, with the genus first established by Loew in 1866.
Asiloidea
asiloid flies
Asiloidea is a large superfamily of true flies (Diptera: Brachycera) with cosmopolitan distribution. It comprises approximately 11 families including the well-known Asilidae (robber/assassin flies), Bombyliidae (bee flies), Therevidae (stiletto flies), Mydidae (mydas flies), and Scenopinidae (window flies). Adult morphology is characterized by antennae with no more than 4 flagellomeres, leg empodium usually setiform or absent, and wing venation featuring an elongate cell cup with vein CuA2 ending freely or meeting A1 near the wing margin. Larval synapomorphies include posterior spiracles arising dorsally from the penultimate abdominal segment and, in most families except Bombyliidae and Hilarimorphidae, a modified cranium forming a hinged metacephalic rod.

Caenotus is a genus of small, slender flies in the family Scenopinidae, commonly known as window flies. These insects are part of the subfamily Caenotinae and are characterized by their reduced wing venation and elongated bodies. The genus was established by Cole in 1923 and contains species primarily found in arid and semi-arid regions.
Mexigonus
Mexigonus is a genus of jumping spiders (family Salticidae) first described by G. B. Edwards in 2003. The genus name references Mexico, where the first identified species were discovered. As of 2019, it contains four species distributed in Mexico and the southwestern United States. The genus is characterized by small body size and typical salticid morphology.
Mydidae
Mydas flies, Mydaid flies
Mydidae, or mydas flies, are a small cosmopolitan family of large to very large flies within the superfamily Asiloidea. With approximately 471 described species, they represent one of the most distinctive dipteran groups due to their exceptional size—Gauromydas heros is the largest known fly species—and their frequent mimicry of stinging hymenopterans, particularly spider wasps. Most species inhabit arid and semiarid regions globally. The family is poorly studied, with larval biology documented for only a handful of species.
Okanagana magnifica
Okanagana magnifica is a species of cicada in the family Cicadidae, described by Davis in 1919. It is native to western North America, with documented occurrences in Arizona, California, Colorado, Nevada, and New Mexico. The species belongs to the genus Okanagana, which comprises annual cicadas rather than periodical species. As with other Okanagana species, it likely inhabits arid and semi-arid environments characteristic of its southwestern range.
Stenostrophia
Stenostrophia is a genus of longhorn beetles (Cerambycidae) in the subfamily Lepturinae, established by Casey in 1913. The genus contains at least three recognized species distributed in western North America. Members are associated with flowering plants in arid and semi-arid habitats. One subspecies, Stenostrophia tribalteata sierrae, has been documented from the Washoe Lake area in Nevada.
