Field Notes
Description:
The caterpillars only feed on a few species of Dutchman's Pipe vines (Aristolochia). Alkaloids in the vines are poisonous to most other things, which makes the caterpillars unpalatable to predators. 2nd photo shows an early instar in an inflorescence, third is a more mature instar.
Habitat:
Dry river beds
