Starry Fireflies are creatures from The Legend of Zelda: Skyward Sword. They can be found on various islands in The Sky at night. Starry Fireflies are generally calm, but will fly away or up higher if Link draws too close too quickly. The easiest way to net them is to sneak up on them slowly, using his Z-target to follow them and make sure he swings the net at them rather than at the ground. In his room at the Knight Academy, Strich will buy Link's excess Fireflies for 30 Rupees each at night.
