description Palamedes Swallowtail Overview
The Palamedes Swallowtail (Papilio palamedes) is a large butterfly native to the southeastern United States, recognized by its dark brown wings marked with yellow spots. Adult wingspans can reach up to 5.5 inches, making it one of the larger swallowtail species in its geographic range. The butterfly's survival is closely tied to Lauraceae plants, specifically red bay and swamp bay trees, which serve as the primary host plants for its larvae. This strict dietary dependence makes the species particularly vulnerable to habitat loss and to the widespread die-off of red bay trees caused by the invasive laurel wilt fungus.
