Battus philenor

The larvae of the blue butterfly (Plebejus icaroides) feed only on lupines, rich in alkaloids. As far as we know, the larvae do not sequester or store the dietary alkaloids (506). Helopeltis feeds on Cinchona bark, which is rich in cinchonine-like alkaloids it stores and uses them for its own defense (506). Larvae of the butterflies Pachlioptera aristolochiae, Zerynthia po-tyxena, Ornithoptera priamus, and Battus philenor live on Aristolochia plants and were shown to take up and sequester aristolochic acid, a carcinogenic alkaloid discussed earlier, as an effective defense compound (4,28,236).
