Isabella's longwing, Isabella's heliconian
Eueides isabella is a large nymphalid butterfly in the Heliconiinae subfamily, found from Mexico through the Amazon basin and the West Indies. Adults are active year-round in tropical habitats and are known to fly even in low light conditions. The species exhibits classic heliconiine traits including long adult lifespan and specialized pollen-feeding behavior. Caterpillars are gregarious, with distinctive white and black coloration and long black spines.
Papilio appalachiensis
Appalachian Tiger Swallowtail
Papilio appalachiensis is a swallowtail butterfly endemic to the Appalachian Mountains of eastern North America. It originated through hybrid speciation between Papilio canadensis and Papilio glaucus, and is now recognized as a distinct species with stable populations at higher elevations. Adults are notably larger than both parental species, with wingspans of 86–115 mm. The species is univoltine, with adults emerging in May and females ovipositing during a brief spring flight period.
