Our Butterfly of the Week is one of the big ones! It’s the giant swallowtail. These butterflies have a wingspan of about 5.5-6.9 inches for females and up to 5.8-7.4 inches for males. Their wings are dark brown/black with yellow markings and small dots of orange/red on their hindwings. Although the giant swallowtail caterpillars love eating citrus leaves, the adult butterflies generally prefer nectar from the flowers inside the pavilion instead of the orange slices in the feeding trays. Read more giant swallowtail fun facts below before visiting them at SOAR.
