Iridopsis clivinaria
mountain mahogany looper moth
Iridopsis clivinaria is a geometrid moth commonly known as the mountain mahogany looper moth. Adults have a wingspan of approximately 22–25 mm. The species has a single annual generation and is active from spring through early summer. Larvae are specialized feeders on woody shrubs in western North America.
Malacorhinus
Malacorhinus is a genus of skeletonizing leaf beetles in the family Chrysomelidae, established by Jacoby in 1887. The genus contains approximately 30 described species distributed across North America and the Neotropics. One species, Malacorhinus irregularis, was introduced to Northern Territory, Australia in 2000 as a biological control agent against the invasive weed Mimosa pigra.
Metrioidea brunnea
Corn Silk Beetle
Metrioidea brunnea, commonly known as the corn silk beetle, is a skeletonizing leaf beetle in the family Chrysomelidae. It is native to North America and feeds on corn silk and foliage. The species is recognized as a minor agricultural pest of maize. Limited detailed biological information is available for this species.
Trirhabda flavolimbata
Coyote Brush Leaf Beetle
Trirhabda flavolimbata, commonly called the coyote brush leaf beetle, is a skeletonizing leaf beetle in the family Chrysomelidae. It is restricted to California where it inhabits coastal scrublands and chaparral. Both larvae and adults are metallic green and sequester toxins from their host plants, rendering them unpalatable to predators. The species has a single annual brood with a distinctive life cycle involving extended egg diapause.
Trirhabda sericotrachyla
California sagebrush leaf beetle
Trirhabda sericotrachyla is a species of skeletonizing leaf beetle in the family Chrysomelidae, first described by Blake in 1931. It is known from western North America, with records from British Columbia and California. The species is associated with California sagebrush (Artemisia californica) as a host plant, reflecting the genus-wide pattern of specialization on Asteraceae. Like other Trirhabda species, adults feed externally on leaves while larvae skeletonize foliage between the veins.
