Thunderwing Butterfly (068 in the standard Breath of the Wild Hyrule Compendium) is a type of butterfly found in Breath of the Wild and Hyrule Warriors: Age of Calamity.
Breath of the Wild
"This rare butterfly only shows itself when it rains. The organs in its body produce an insulating compound. When made into an elixir, it offers electrical resistance."
Thunderwing Butterflies can typically be found in areas which frequently suffer from thunderstorms, such as in the Faron region. They can be sold to shop-vendors all over Hyrule for 2 Rupees each, but, alternatively, they can be used to concoct Electro Elixirs, which increase Link's shock resistance.
