The wing underside resembles a dead leaf, on Sorbus sitchensis in this instance.

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 browns and greys of the wing underside make it resemble a dead leaf when the wings are closed. Its wingspan varies from 3.2--7 cm (1¼--2¾ inches).[1]
