Shadow Insect

Shadow Insects (also known as Twilit Parasites) are enemies from The Legend of Zelda: Twilight Princess. They are insect-like Twilight creatures invisible to Humans. Only honed animal senses can see them when in the Twilight Realm. Shadow Insects are electric and sparked purple. Once one is defeated, it releases one of the Tears of Light, which have the power to restore light to the spirits Faron, Eldin and Lanayru after their light have been stolen by shadow beasts. Although humans cannot directly see them, they can see the electricity around them when they move.
