Fast Facts:
Despite the name, the host plants of the Sagebrush Checkerspot caterpillars are Rabbitbrush and Desert Aster. Caterpillars will eat the leaves and flowers of the plant.
Some caterpillars hibernate under rocks, and some diapause, meaning they are able to remain in the caterpillar stage, for months or years, to survive bad weather.
Adult butterflies typically have a lifespan of ~30 days.
This species belongs to the Nymphalidae family, which is also known as brushfooted butterflies. There are multiple subspecies of Checkerspot butterflies, found across the United States.
