Chnaunanthus chapini
Chnaunanthus chapini is a species of scarab beetle described by Saylor in 1937. It belongs to the subfamily Melolonthinae, commonly known as May beetles or June beetles. The species is known from limited records in California, USA. Very few observations of this species have been documented.
Choristostigma zephyralis
Choristostigma zephyralis is a small crambid moth described from California in 1914. Adults are distinguished by bright sulphur yellow forewings shading to orange yellow at the termen, with prominent purple markings including a costal stripe extending to the reniform spot. The hindwings are sulphur yellow with dark subbasal, discal, and subterminal lines plus purplish suffusion beyond the subterminal line. The species has a wingspan of approximately 23 mm. Larvae feed on Monardella villosa, a California native mint.
Chortophaga mendocino
Mendocino Green-striped Grasshopper
Chortophaga mendocino is a band-winged grasshopper in the family Acrididae, first described by Rentz in 1977. It is endemic to California and closely related to the more widespread Chortophaga viridifasciata (green-striped grasshopper). The species is poorly studied compared to its congeners, with limited published information on its biology and ecology.
Chrysocharis wahli
Chrysocharis wahli is a species of parasitoid wasp in the family Eulophidae, described from California in 1995. The genus Chrysocharis comprises small chalcid wasps that parasitize leaf-mining insects. This species is known only from the type locality in California and remains poorly studied.
Cibdelis blaschkei
Cibdelis blaschkei is a North American darkling beetle in the subfamily Stenochiinae. The immature stages were first described in 2014, revealing distinctive defensive structures and saproxylic ecology. The species inhabits forested regions of California, where larvae develop in soft rotten dry wood of dead branches. Both larvae and pupae possess urogomphi—abdominal armature that can be raised and curved forward as antipredator defenses. The complete life cycle has been documented through rearing adults from pupae with associated larval exuvia.
Cicindela senilis
Senile Tiger Beetle
Cicindela senilis, commonly known as the senile tiger beetle, is a species of tiger beetle endemic to western California. It inhabits specialized saline environments including tidal mud flats, coastal salt marshes, and inland salt marshes. The species is recognized to have three subspecies: C. s. senilis (nominate), C. s. exoleta, and C. s. frosti. Subspecies frosti has been documented in Lake Elsinore and several counties in southern California including Los Angeles, Orange, San Bernardino, and San Diego.
Cicindela tranquebarica inyo
Inyo Tiger Beetle, Oblique-lined Tiger Beetle (Inyo subspecies)
Cicindela tranquebarica inyo is a subspecies of tiger beetle in the family Carabidae (subfamily Cicindelinae). It belongs to the widespread Oblique-lined Tiger Beetle species complex, which occurs across North America in sandy and open habitats. This subspecies was described by Fall in 1917 and is associated with the Inyo region of eastern California. Tiger beetles in this group are fast-running, visually oriented predators that hunt small invertebrates. The subspecies status indicates geographic differentiation within the broader C. tranquebarica distribution, though like many tiger beetle subspecies, its taxonomic validity may require further study.
Cicindela tranquebarica sierra
Sierra Tiger Beetle
The Sierra Tiger Beetle is a montane subspecies of the common tiger beetle Cicindela tranquebarica, restricted to the Sierra Nevada mountains of California. It represents a high-elevation form distinguished from lowland populations by its coloration and habitat association. Like other tiger beetles, it is a fast-running, visually oriented predator active during daylight hours. The subspecies designation reflects both geographic isolation and morphological differentiation from nominate C. tranquebarica populations.
Cicindela tranquebarica viridissima
Greenest Tiger Beetle
Cicindela tranquebarica viridissima is a highly localized subspecies of the widespread Oblique-lined Tiger Beetle, distinguished by its exceptionally bright metallic green coloration. Formerly ranging along much of the Santa Ana River from Orange County to Mentone and possibly the San Jacinto River, it now survives only in two small populations: along the Santa Ana River adjacent to Riverside, and near Bautista Creek in Hemet, California. Adults exhibit a distinctive life cycle with fall emergence, winter dormancy underground, and spring re-emergence for reproduction.

Coenonympha tullia california
California Ringlet
Coenonympha tullia california is a subspecies of the Common Ringlet butterfly, historically found in low-elevation areas of central and northern California. According to long-term monitoring by UC Davis professor Art Shapiro, this subspecies was regionally extirpated from the Sacramento Valley and surrounding lowlands by 2007, becoming one of several butterfly species to disappear from Shapiro's study transect between Chico and Stockton. The decline is attributed to climate change disrupting diapause cues and pesticide exposure, particularly neonicotinoids. The subspecies exemplifies broader patterns of butterfly population collapse documented across North America.

This subspecies occurs in California and exhibits the characteristic red-and-black coloration of C. coralinus, with males showing variable development of black elytral markings (thin to moderately expanded sutural stripes) while females typically display more consistently expanded black areas. Adults emerge in late August and September to feed on yellow flowers of Ericameria nauseosa (gray rabbitbrush), their larval host plant. The subspecies was described by Linsley in 1957 and is one of several geographically segregated populations within the highly polytopic C. coralinus species complex.
Crossidius coralinus caeruleipennis
Crossidius coralinus caeruleipennis is a subspecies of longhorned beetle in the family Cerambycidae, tribe Trachyderini. It is considered among the most visually striking of the C. coralinus subspecies due to its bright orange coloration.

valley elderberry longhorn beetle, VELB
Desmocerus aureipennis piperi, commonly known as the valley elderberry longhorn beetle (VELB), is a federally threatened subspecies endemic to California's Central Valley. Adults are active for only a few weeks annually, making detection difficult. The subspecies breeds exclusively in living stems and roots of elderberry plants (Sambucus spp.). Males are attracted to a sex pheromone, (R)-desmolactone, which has proven effective for monitoring populations.
Deuterophlebia shasta
Deuterophlebia shasta is a species of mountain midge in the family Deuterophlebiidae, first described by Wirth in 1951. This family represents one of the most primitive lineages of true flies (Diptera), with larvae that are highly specialized for life in cold, fast-flowing mountain streams.
