Unlike other insect species, butterflies can see a full range of color. This helps them locate favorite flowers. Some may prefer certain colored flowers over others. The Swallowtail group contains several different species, including the largest butterfly in the world, Queen Alexandra's Birdwing. It measures 11 inches across. The butterfly pictured here is the more common Tiger Swallowtail., which inhabits deserts, grasslands, forests, and gardens alike. Swallowtails are a unique group of butterflies, and their welfare is considered a reflection of the quality of their environment. These butterflies reflect ecological trends in tropical rainforests. The Queen Alexandra's Birdwing is now classified as an endangered species. The biggest threat to Swallowtails is deforestation, with commercial collection and poaching not far behind.
