The slow-flying wood white butterfly (Leptidea sinapis) is a small white butterfly that is primarily found in clearings among woodlands or nearby shrubbery – mainly in England, Ireland, and Northern Europe. It has white wings with grey or yellow markings near the center or tip of the wing. When at rest, the rounded tips of the forewings provide one of the main distinguishing features between this butterfly and other "whites". Adults always rest with their wings closed. In flight, the male can be distinguished from the female by a black spot at the tip of the forewings that is greatly reduced in the female.
