Deku Hornets are creatures from The Legend of Zelda: Skyward Sword. Unlike most bugs in the game, they will attack Link and thus can be considered enemies in addition to items (making them similar to catchable Bees in A Link to the Past and A Link Between Worlds). They deal a quarter-heart of damage to Link every time they sting him. Strich will buy Link's excess Hornets at night in his room at the Knight Academy. Because of their sheer numbers, he will only pay one Rupee each for them.
