Identification

The wingspan is 60–65 mm.[3] The forewings are yellowish on the bottom, gradually morphing into white on the top. The veins are black at the tips and there is a black eyespot on each wing with a white center. The hindwings are yellow orange with black-tipped veins and a thick black stripe that curves through the middle of the wing, up through the forewings. There is a small black eyespot in the middle of each wing. The body is yellow orange.

Life history

The eggs are laid in rings around small twigs of the host plant. The larvae have been recorded feeding on Purshia tridentata, Symphoricarpos species and Ribes species. The larvae are black and are covered with yellow spines that will sting on contact with skin.
