Which species is a swallowtail butterfly?

• A. Tiger Swallowtail Butterfly
• B. Viceroy Butterfly
• C. True Armyworm
• D. Walking Stick

Answer: (A)

Swallowtail butterflies are in the Papilionidae family and are known for the tail-like projections on their hindwings. The Tiger Swallowtail is a classic example of this group, a large butterfly with the distinctive yellow and black pattern and the hindwing tails that mark it as a true swallowtail.

The Viceroy, while similar in size and color, is not a swallowtail — it belongs to a different butterfly family and does not have the long tails on the hindwings. The True Armyworm is not a butterfly at all; it’s the larval stage of a moth. The Walking Stick is an insect in a different order (it imitates a twig and has no butterfly traits). So the species that is a swallowtail butterfly is the Tiger Swallowtail.
