The Valley of the Butterflies, a unique natural site on Paros comprises a rare biotope for Jersey Tiger Moth butterflies, which can be seen perched in large numbers on the tree trunks. The butterflies of Paros are known for their wonderful coloring (brown-black with yellowish extremities and bright red wings) and appear from late May to late July, disappear in August and reappear in September. The disappearance is due to the females seeking places to lay their eggs and die.
A small admittance fee is charged at the entrance of the valley, and visitors are advised to keep as quiet as possible so as not to startle the beautiful inhabitants of the forest and force them to consume the energy that they require to complete their mission.
