The caterpillars will reveal two yellow horns near it's head, if disturbed. If a bird picks up the caterpillar, the taste emanating from these horns is distasteful to the bird and is a protection to the caterpillar. This caterpillar is feeding on my Pipevines: Aristolochia durior and Aristolochia baetica.
The butterflies are laying eggs on the host plants, so I assume these caterpillars pupated over the winter, came out in the spring & have grown large enough to pupate while the butterflies are laying their eggs.
