Abstract
Abdominal defensive glands of both sexes of the Gulf fritillary butterfly, Agraulis vanillae (Linnaeus) (Nymphalidae:Heliconiinae) emit a pronounced o dor when disturbed. We have identified 6-methyl-5-hepten-2-one; oleic, palm itic, and stearic esters of the corresponding alcohol 6-methyl-5-hepten-2-o l; hexadecyl acetate; 1,16-hexadecanediol diacetate; and 1,15-hexadecanedio l diacetate in the glandular exudate. Since we have determined that free-fl ying birds or birds in a butterfly conservatory discriminate against A. van illae as prey, we suggest that the constituents in the glands may play a de fensive role against potential avian predators.
