Dasychira grisefacta
Grizzled Tussock Moth, Pine Tussock
Dasychira grisefacta is a tussock moth in the family Erebidae, first described by Harrison Gray Dyar Jr. in 1911. Males have functional wings with a wingspan of approximately 42 mm, while females are wingless. The species is associated with coniferous forests and has a broad distribution across western North America. Larvae feed on several genera of conifers including Douglas-fir, hemlock, spruce, and pine.
Dasymutilla asopus
Dasymutilla asopus is a species of velvet ant in the family Mutillidae. Like all mutillids, females are wingless while males possess wings. The species exhibits the bright aposematic coloration typical of the genus, warning predators of its potent sting. As a parasitoid wasp, females seek out ground-nesting hosts to deposit their eggs. The species occurs across western North America, with confirmed observations from multiple states and provinces.
Dasypyga alternosquamella
snout moth
A specialist snout moth (Pyralidae: Phycitinae) endemic to western North America. Described by Ragonot in 1887, this species has evolved a strict ecological dependency on dwarf mistletoes (Arceuthobium). Its larvae are obligate herbivores that mine mistletoe shoots, often killing the host plant. The species represents a notable case of host-specific herbivory with measurable ecological impacts on mistletoe populations.
Decodes macdunnoughi
Decodes macdunnoughi is a species of tortricid moth in the tribe Cnephasiini, described by Jerry A. Powell in 1980. The genus Decodes contains approximately 20 described species distributed primarily in western North America. As a member of the leafroller moth family Tortricidae, this species likely exhibits the typical resting posture with wings held roof-like over the body.
Decticita
shield-backed katydids
Decticita is a genus of shield-backed katydids in the family Tettigoniidae, established by Hebard in 1939. The genus contains at least three described species distributed in western North America, particularly California.

It belongs to the large and diverse subfamily Deltocephalinae, which contains many economically significant agricultural pests. The species has been documented in western North America from British Columbia to California and eastward to Kansas and Colorado. Like other members of its genus, it is presumed to feed on plant phloem sap using piercing-sucking mouthparts, though specific host plants remain unverified.
Deltocephalus vanfus
Deltocephalus vanfus is a species of leafhopper in the family Cicadellidae, described by Kramer in 1971. It belongs to the large subfamily Deltocephalinae, a group known for their association with grasses and sedges. The species has been documented in western North America.
Deltopauropus
Deltopauropus is a genus of minute myriapods in the family Brachypauropodidae, established by MacSwain and Lanham in 1948. Pauropods in this genus are among the smallest terrestrial arthropods, inhabiting soil and leaf litter. As members of the order Tetramerocerata, they possess four antennal segments. The genus is rarely encountered due to its cryptic lifestyle and minute size.
Dendroctonus brevicomis
Western Pine Beetle
Dendroctonus brevicomis, commonly known as the western pine beetle, is a destructive bark beetle species in the family Curculionidae. It is a major pest of ponderosa pine (Pinus ponderosa) and Coulter pine (Pinus coulteri) in western North America. The species is known for causing extensive tree mortality during outbreaks, with documented losses of 60–90% of host trees in affected landscapes. A notable outbreak occurred in the central and southern Sierra Nevada Range from 2014 to 2017, killing millions of ponderosa pines. The beetle plays a significant role in forest dynamics but also poses substantial economic and ecological challenges.
Dendroctonus jeffreyi
Jeffrey pine beetle
Dendroctonus jeffreyi is a bark beetle in the family Curculionidae, subfamily Scolytinae, endemic to western North America. The species is monophagous on Jeffrey pine (Pinus jeffreyi), feeding on phloem and causing significant tree mortality during outbreak conditions. Adults bore into bark to create egg chambers, with larvae developing in galleries under the bark. The beetle possesses specialized mycangia for transporting the symbiotic fungus Ophiostoma clavigerum, which contributes to tree mortality. Populations show genetic structure across their range, with southern California populations most differentiated.
Dendroctonus ponderosae
Mountain Pine Beetle
Dendroctonus ponderosae, commonly known as the mountain pine beetle, is a bark beetle native to western North America. It is a significant forest disturbance agent that attacks and kills pine trees, particularly during outbreak conditions. The beetle has a hard black exoskeleton and measures approximately 5 mm. Population success is heavily influenced by temperature, which drives phenology and adult emergence synchrony required for mass attacks on host trees. The species has been responsible for extensive tree mortality across millions of acres in the western United States and Canada.
Dendroctonus pseudotsugae
Douglas-fir beetle, Douglas fir beetle
The Douglas-fir beetle (Dendroctonus pseudotsugae) is a bark beetle native to western North America and a major pest of Douglas-fir (Pseudotsuga menziesii). Adults are small (4.4–7 mm), light brown when young, darkening to brown or black with reddish wing covers. Outbreaks typically follow disturbances such as storms, fire, or drought, which provide stressed or dead host trees. The species has one of the most thoroughly studied pheromone systems among bark beetles, with operational use of its antiaggregation pheromone (MCH) to protect high-value trees developed over 40 years of research. The beetle also infests downed western larch (Larix occidentalis), though brood do not survive in live larch due to high 3-carene content.
Deraeocoris fulgidus
Deraeocoris fulgidus is a species of plant bug in the family Miridae, first described by Van Duzee in 1914. It belongs to the diverse genus Deraeocoris, which contains predatory and plant-feeding species. Records indicate presence in western North America, particularly California, Colorado, and Nevada. Available information on this species is limited compared to better-studied congeners.

nevadensis bakeri
Baker's Nomia
Baker's Nomia is a subspecies of the Nevada nomia, a sweat bee in the family Halictidae. It was described by Cockerell in 1898 and is distinguished from the nominate subspecies by morphological characteristics. The subspecies occurs in western North America, where it is associated with alkali and saline habitats. Like other Dieunomia species, it is a ground-nesting bee with specialized ecological requirements.
Digrammia californiaria
California granite moth, Californian granite
Digrammia californiaria, commonly known as the California granite moth or Californian granite, is a geometrid moth native to western North America. The species was first described by Packard in 1871 and is part of the diverse Ennominae subfamily within Geometridae. It has been documented in blacklighting surveys in California, where it can occur in notable numbers during peak flight periods.
Digrammia colorata
creosote moth
Digrammia colorata, commonly known as the creosote moth, is a species of geometrid moth in the family Geometridae. It is native to arid regions of western North America where its larvae feed on creosote bush (Larrea tridentata), a relationship reflected in its common name. The species has been documented in Middle America and North America according to distribution records. It is one of approximately 4,000 species in the genus Digrammia, which are generally small to medium-sized moths with cryptic coloration.
Digrammia irrorata
Pale-lined Angle
Digrammia irrorata is a geometrid moth species first described by Alpheus Spring Packard in 1876. It occurs across western North America from Oklahoma to California, extending north into southwestern Canada. The species has a wingspan of 23–26 mm. Adults are active from March through June in northern populations, with multiple generations occurring in southern portions of the range.
Digrammia subminiata
Vermilion Granite Moth, vermillion granite, dark-waved angle
A small geometrid moth of western North America, first described by Alpheus Spring Packard in 1873. Adults are active in late spring and summer. The species is associated with willow hosts.
