Taiwan is lucky to have an amazing diversity of fireflies—over 65 species. It also has the largest density of these amazing beetles in Asia—two species of firefly for every 386 sq mi (1,000 sq km). No wonder, observing glowing fireflies has become a national sport in an island country. Every April, dozens of firefly watching festivals take place in all regions, from Taipei in the North to Kenting National Park in the South.
