A valley in Songhe village of Dali city in southwest China's Yunnan province sees an "invasion" of hundreds of millions of beautiful butterflies every summer, hence the nickname "butterfly valley".
Since the closure of several small private coal mines in the area 20 years ago, the surrounding ecological environment has improved significantly, paving the way for the butterfly to appear. The valley has seen an increase in butterfly numbers since May 2000, with a steady influx of butterflies arriving in the valley each summer.
Butterfly Valley is most famous for its black-striped white butterflies. It is home to many species, of different sizes and colors. Countless colorful butterflies fluttering in the wind make the valley a fascinating destination for all visitors.
