Aeoloplides tenuipennis
narrow-winged saltbush grasshopper, narrow-winged bush grasshopper
A spur-throated grasshopper specialized on chenopod plants, particularly saltbushes (Atriplex species). It inhabits arid and semi-arid regions of the southwestern United States and northern Mexico, where it feeds on plants often considered noxious weeds, including Russian thistle (Salsola tragus). The species is generally regarded as beneficial or innocuous in rangeland settings rather than a crop pest.

Aeoloplides turnbulli
thistle grasshopper, Russian thistle grasshopper, saltbush grasshopper
Aeoloplides turnbulli is a medium-sized, robust spur-throated grasshopper in the family Acrididae, commonly known as the thistle grasshopper or Russian thistle grasshopper. The species exhibits two recognized subspecies: A. t. turnbulli in the north and A. t. bruneri in the south, distinguished primarily by wing length. It is an early-hatching species with a prolonged nymphal development period of 50–60 days. The species has demonstrated outbreak potential, with historical population irruptions documented in western Kansas during the 1930s and in the Big Horn Basin, Wyoming, in 1993.

Anthocoris tomentosus
Anthocoris tomentosus is a minute pirate bug in the family Anthocoridae, a group of predatory true bugs. Like other members of the genus Anthocoris, it is a small insect that preys on other small arthropods. The species is found in North America, including western regions and areas of California. Specific details about its biology and ecology are limited in published literature.

Auplopus
spider wasps
Auplopus is a large genus of small spider wasps in the family Pompilidae, distributed worldwide except Antarctica. Females construct distinctive barrel-shaped mud nests, often inside pre-existing cavities such as abandoned nests of other wasps, hollows in wood, or rock crevices. They hunt spiders, paralyze them with venom, and amputate the legs before transporting the prey to their nests. The wasps provision each mud cell with one or more paralyzed spiders, lay a single egg on the final victim, and seal the cell. Auplopus species are solitary and non-aggressive, with most activity occurring from May to October.

Bembidion quadrimaculatum
Garden Bembidion Beetle
Bembidion quadrimaculatum is a small ground beetle in the family Carabidae with a broad distribution spanning Europe, Northern Asia, North America, and Southern Asia. The species is recognized as an important component of agricultural ecosystems, where it serves as a beneficial predator. Multiple subspecies have been described, including the nominate B. q. quadrimaculatum and the North American B. q. oppositum. Populations have been observed to respond positively to conservation tillage practices in agricultural settings.

Bembidion quadrimaculatum oppositum
Bembidion quadrimaculatum oppositum is a subspecies of ground beetle in the family Carabidae. It was described by Thomas Say in 1823, originally as Bembidium oppositum. The subspecies has been documented in agricultural studies as a beneficial ground beetle sensitive to soil management practices. Historical distribution records indicate presence across parts of Europe, Asia, and North America including Alaska, though specific habitat associations remain poorly documented.

Blissus occiduus
Western Chinch Bug
Blissus occiduus, the western chinch bug, is a phloem-feeding true bug (Hemiptera: Blissidae) that is a significant pest of warm-season turfgrasses, particularly buffalograss and zoysiagrass. The species exhibits strong host preference hierarchies, with buffalograss being the most preferred host followed by zoysiagrass, though it can survive and reproduce on a broad range of grasses including agronomic crops. Field studies have documented inconsistent control with neonicotinoid insecticides, with thiamethoxam showing particularly rapid degradation in buffalograss tissues compared to imidacloprid and clothianidin.

Brochymena myops
rough stink bug, tree stink bug
Brochymena myops is a species of rough stink bug native to North America, belonging to the genus Brochymena commonly known as "tree stink bugs" for their bark-like camouflage. The species ranges from Quebec to Florida and westward through the central United States to Texas. Adults are active during warm periods throughout the year, including winter sunny days, and are frequently mistaken for the invasive brown marmorated stink bug. Like other Brochymena species, B. myops is not considered an agricultural or household pest.

Cantharidae
Soldier Beetles, Leatherwings
Soldier beetles (Cantharidae) are soft-bodied, elongate beetles with flexible, velvety elytra that give rise to the common name 'leatherwings.' The family is cosmopolitan, with approximately 160 species in 11 genera occurring in California alone. Adults are frequently observed on flowers, particularly in late summer and fall, where they feed on pollen and nectar and prey on small insects. Both adults and larvae produce defensive chemicals from specialized glands, making them distasteful to predators. The common name derives from the red-and-black color pattern of some species, reminiscent of British military uniforms.
