The California Tortoiseshell (Nymphalis californica) is a butterfly of the Nymphalidae family.
The California Tortoiseshell is known for having population explosions which cause the butterflies to migrate to new areas. The cause of these seemingly random population explosions is unknown. Their larvae eat various species of Ceanothus.
It is recognized for the top of its wings being orange with big black spots (used mainly for camouflage). The underside of its wings look literally like a dead leaf, because when it has its wings up during rest it looks like a dead leaf on the ground. Its wingspan varies from 3.2–7 cm (1¼–2¾ inches).
