The California tortoiseshell (Nymphalis californica) is a butterfly of the family Nymphalidae.

The wings of the California tortoiseshell have ragged edges. The upper sides of the wings are orange with black spots and a wide black margin. The undersides of the wings are a mottled dark brown. Its wingspan varies from 3.2 to 7 cm (1+142+34 inches). [1] [2]

Caterpillars are black with white spots and hairs. Each segment of the body has seven spines. They eat various species of Ceanothus . [1]

This butterfly is known for having irregular population explosions. [1] Ravens commonly prey on California tortoiseshells in population explosions during outbreak years. [3]

<span class="mw-page-title-main">Nymphalidae</span> Largest butterfly family

The Nymphalidae are the largest family of butterflies, with more than 6,000 species distributed throughout most of the world. Belonging to the superfamily Papilionoidea, they are usually medium-sized to large butterflies. Most species have a reduced pair of forelegs and many hold their colourful wings flat when resting. They are also called brush-footed butterflies or four-footed butterflies, because they are known to stand on only four legs while the other two are curled up; in some species, these forelegs have a brush-like set of hairs, which gives this family its other common name. Many species are brightly coloured and include popular species such as the emperors, monarch butterfly, admirals, tortoiseshells, and fritillaries. However, the under wings are, in contrast, often dull and in some species look remarkably like dead leaves, or are much paler, producing a cryptic effect that helps the butterflies blend into their surroundings.

<span class="mw-page-title-main">Small tortoiseshell</span> Species of butterfly in the family Nymphalidae

The small tortoiseshell is a colourful Eurasian butterfly in the family Nymphalidae. Adults feed on nectar and may hibernate over winter; in warmer climates they may have two broods in a season. While the dorsal surface of the wings is vividly marked, the ventral surface is drab, providing camouflage. Eggs are laid on the common nettle, on which the larvae feed.

<i>Nymphalis antiopa</i> Species of butterfly

Nymphalis antiopa, known as the mourning cloak in North America and the Camberwell beauty in Britain, is a large butterfly native to Eurasia and North America. The immature form of this species is sometimes known as the spiny elm caterpillar. Other older names for this species include grand surprise and white petticoat. A powerful flier, this species is sometimes found in areas far from its usual range during migration.

<i>Adelpha californica</i> Species of butterfly

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.

<i>Nymphalis</i> Genus of butterflies

Nymphalis, commonly known as the tortoiseshells or anglewing butterflies, is a genus of brush-footed butterflies. The genera Aglais, Inachis, Polygonia and Kaniska, were sometimes included as subgenera of Nymphalis but they may instead be treated as distinct genera. See also anglewing butterflies.
