Pest Status: Swallowtail butterflies are not pests.
Appearance: Swallowtails are large, beautiful, butterflies that have distinctive yellow-and-black wings with a long "tail" on the end of each hindwing.
Life Cycle: Females lay their eggs on the undersides of leaves. Eggs hatch within two weeks into tiny caterpillars that take about one month to grow to full size. A pupa takes about 24 hours to complete development.
Where to Collect: Swallowtails are often found flying in rural areas where there are plenty of diverse plants. They are strong fliers, but usually can be netted by agile and patient collectors.
