Taiwan Beech Hairstreak

The rare Taiwan beech tree grows only in a few forests of northern Taiwan. These are also the only places you'll find a Taiwan Beech Hairstreak. This striking butterfly depends on the tree for survival. But the butterfly is so rare, collectors will cut down trees to get its eggs. Both the butterfly and the tree are at risk of becoming extinct. To save them, Taiwan has set up a nature reserve to protect the entire ecosystem.
