Purple Crow Butterflies are rare migratory butterflies that arrive according to schedule each winter at the Purple Butterfly Valley in Maolin to pass the winter. In the river valleys in Maolin and Liugui, which provide shelter for the butterflies, you can find the colorful Striped Blue Crow, Double-Branded Black Crow, Dwarf Crow, the Euploea eunice and even the Chestnut Tiger butterfly of even more colors.

A this period of time each year, to meet the needs of the public, the Administration provides volunteer guides at the entrance to Purple Butterfly Valley and also broadcasts live videos of Purple Crow Butterflies in the Visitor’s Center exhibition room. To learn more about the ecology of these migratory butterflies, besides reading descriptions and looking at diagrams in the exhibition room, volunteer guides will also be glad to answer any questions visitors have.

The number of visitors who have registered online to view our world-class butterfly sights in the 2008-2009 Maolin Purple Butterfly Valley—Two-Year Butterfly Viewing event has already surpassed 4,000.  The Maolin National Scenic Area Administration is dedicated to promoting ecological tourism in a sustainable way, so the butterfly-viewing event will continue to be held. Through the detailed description of ecology guides, visitors will learn about our world-class butterfly panorama!
