The wingspan is about 30mm (1.2in). They are tan to gray moths with prominent wing veins. Adults are on wing from March to November. There are two generations per year in northern California. Sometimes there is a third generation in southern California.
The larvae feed on the leaves of oak, especially Quercus agrifolia (coast live oak). Young larvae feed between veins on the lower leaf surface. Although the upper leaf surface is left intact, it dries out and turns brown. Larvae in later instars chew completely through the leaf blade, often leaving only major leaf veins. Small frass pellets drop from the canopy as larvae feed. In outbreak years, individual trees or groups of trees may be almost entirely defoliated, typically by late summer or early fall. The larvae are black with lengthwise yellow stripes. Full-grown larvae are about 30mm (1.2in) long. Pupation takes place in a white or yellow pupa with black markings.

The species is known for its wooly body and pink and yellow coloration, which varies from cream or white to bright pink or yellow. Males have bushier antennae than females, which allow them to sense female pheromones for mating.
Adelpha californica, the California sister, is a species of butterfly in the family Nymphalidae. They are common in California, but can also be found in western Nevada and Oregon, as well as in northern Baja California. The upper surfaces of their wings are dark brown to black with wide cream white bands dissecting both wings and two orange patches near the tips of the forewings. The underside is variously colored with browns, blue, orange, and white. A. californica is unpalatable to predators and is part of a large mimicry complex.

They are also found in Southeastern Alaska.
Dasychira basiflava, the yellow-based tussock, is a moth of the family Erebidae. The species was first described by Alpheus Spring Packard in 1865. It is found in North America from Massachusetts and southern Ontario west to Iowa, Texas, south to South Carolina and possibly Florida. It is also found in Southeastern Alaska.

It is found in North America from Nova Scotia to Florida, west to Texas and north to Saskatchewan.
Bucculatrix thoracella, the lime bent-wing, is species of moth in the family Bucculatricidae, and was first described in 1794 by Carl Peter Thunberg as Tinea thoracella. It is found throughout Europe with exception of Ireland and the Balkan Peninsula, and in Japan, where it occurs on the islands of Hokkaido and Honshu.
Phyllonorycter froelichiella is a moth of the family Gracillariidae. It is found in all of Europe, except Greece.
The European oak leaf-miner or Zeller's midget is a moth of the family Gracillariidae. It is found in Europe south of the line running from Ireland, through Great Britain, Denmark to Ukraine. It is also found in Macaronesia. It is an introduced species in New Zealand and Australia.
Datana ministra, the yellownecked caterpillar, is a moth of the family Notodontidae. It is found in southern Canada and the United States east of the Rocky Mountains, in the south-west it ranges to California.
Pheosia rimosa, the black-rimmed prominent moth, fissured prominent or false-sphinx, is a moth of the family Notodontidae. The species was first described by Alpheus Spring Packard in 1864. It is found from coast to coast in North America, although it is less common in the south-eastern United States.
Ennomos magnaria, the maple spanworm moth, notched wing moth, notched-wing geometer or notch-wing moth, is a moth of the family Geometridae. The species was first described by Achille Guenée in 1858. It is found from coast to coast in southern Canada and the northern United States, south in the east to Florida and Louisiana and in the west to California.
The blue copper, also known as Lycaena heteronea, is an American butterfly that belongs to the gossamer-winged family. The butterfly is named so because of the bright blue hue of the upper side of the males' wings. Females are brown on their upper side. Both sexes are white with black spots on the underside of the wings. Blue coppers are seen on the west coast of the United States and the southwest region of Canada, particularly British Columbia and Alberta. The males are often confused with Boisduval’s blue, another species of butterfly. Blue coppers prefer to live in areas where species of Eriogonum are found. Blue copper larvae sometimes form mutualistic associations with Formica francoeuri, an ant species.
Clemensia albata, the little white lichen moth, is a moth of the family Erebidae. It was described by Alpheus Spring Packard in 1864. It is found in eastern North America, west across boreal Canada to south-eastern British Columbia. The range extends along the Pacific Coast south to Monterey Bay in west-central California. The habitat consists of moist forests, including coastal rainforests, oak woodlands and mixed hardwood forests.
Ichneutica nullifera is a moth of the family Noctuidae. This species is endemic to New Zealand and can be found in the Tongariro National Park, along the Wellington coast and throughout the South Island. The adults are large and the forewing of adults can vary in colour from pale fawn to dark grey. The larvae are coloured a bright yellow-brown with a paler underside. The larval host species are in the genus Aciphylla and as a result the adult moths are often found in habitat dominated by species in this genus. Adults are on the wing from November to early April and are sometimes attracted to light.
Pseudohemihyalea edwardsii, or Edwards' glassy-wing, is a moth in the family Erebidae. It was described by Alpheus Spring Packard in 1864.
