California Tortoiseshell,  Nymphalis californica  <LEP126>


     In some years this species swarms in the Sierra Nevada and Cascade Mountains.  The perch shown in the drawing is a common posture for brush-footed butterflies.  It shows part of the orange-brown upperside with its black patches and borders and white spots near the tips.  The underside is mottled brown, tan and frosty.
