According to Fantastic Beasts and Where to Find Them, the Doxy is also known as the "Biting Fairy" and is often mistaken for a fairy though it is a separate species. Like the fairy, the Doxy has a form resembling that of a minature human being. However, unlike the fairy, the Doxy is covered in black hair. Doxies have wings and an extra pair of arms and legs and can lay up to five hundred eggs, which hatch in two or three weeks time, at once. They have double rows of sharp teeth that are venomous enough that an antidote is recomended for anyone bitten by one. Doxies are found throughout northern Europe and North America, as they prefer cold climates to warmer ones.
