Butterwort rosettes possess elongated leaves with curled edges, often without stalks. These leaves are coated with small, oily glands and have a light, yellow-green colour. They are widespread throughout Europe, North America, and certain regions of northern Asia. The majority of Butterwort species can be found in South and Central America.

Although they may not be noticeable, Butterworts use a flypaper-like method to capture prey. Tiny insects become trapped in the sticky mucilage on the leaves and are gradually decomposed after the margins curl over them in approximately 2 hours.
