With warm, sunny weather, summer is usually the peak butterfly season in many regions of the earth. In south China's Hainan Tropical Rainforest National Park and the surrounding areas, all kinds of butterflies can often be seen flitting through clusters of colorful tropical flowers or alighting on the rocks along the valleys or streams.

About 500 species of butterflies have been discovered in Hainan's tropical rainforest and mountain areas, accounting for approximately 87% of all Hainan Island's butterflies. The diversity of an area's butterflies has a close link with the diversity of its plants, with the large number of butterflies in Hainan showing an excellent and stable ecosystem.

Let's take a look at the colorful butterflies spotted this summer in the Wuzhishan area, which is part of the Hainan Tropical Rainforest National Park.
