Firefly Trees, Papua New Guinea
Firefly trees are exactly what they sound like. Along the coasts of rivers in places like Papua New Guinea, India, and Malaysia, fireflies congregate in trees. Not just a handful or couple-dozen fireflies, enough fireflies to light up massive trees like a Christmas tree. They only congregate in the trees to breed, but they have created a spectacle. There are tours given in these places for people to witness the synchronized firefly lights for themselves.
