Females of the Schaus Swallowtail (Papilio aristodemus ponceanus Schaus) lay dark green eggs and light green eggs in an approximately 1:2 ratio in the wild on Elliott Key, Biscayne National Park, southern Florida. This color dimorphism may be maintained as a balanced polymorphism by selection for cryptic matching of new and old growth foliage of the primary larval hostplant, torchwood (Amyris elemifera, Rutaceae).
