Shadow Insects are formed from evil magic, attached to the a piece of the power of a Light Spirit. In each area of Twilight, Wolf Link and Midna must find and kill fifteen (twelve in Twilight Princess HD) to retrieve their stolen power in the form of a Tear of Light and fill a Vessel of Light to restore the light to the province.
Shadow Insects are invisible to the naked eye, and can only be seen with the use of superhumanly-acute senses. Wolf Link can use his senses to locate and obliterate the bugs with Midna's help in order to obtain each Tear of Light.
