The Common Yellow Swallowtail, scientifically known as Papilio machaon, is a striking butterfly found in various regions across the world. It is easily recognizable by its vibrant yellow wings adorned with black edges and blue and orange spots. This butterfly typically inhabits open fields, gardens, and forest edges, where it feeds on nectar from flowers. The life cycle of the Common Yellow Swallowtail includes four stages: egg, larva (caterpillar), pupa (chrysalis), and adult butterfly. The caterpillars are often green or brown, mimicking leaves to avoid predators. These butterflies play a crucial role in pollination, contributing to the health of ecosystems.
