Pinguicula is a genus of carnivorous plants commonly known as butterworts. These plants are characterized by their flat, sticky leaves that trap and digest small insects. They thrive in nutrient-poor environments, using their unique adaptations to supplement their diet. Butterworts are found in various regions around the world, including North America, Europe, and Asia. They typically grow in moist, acidic soils and can be found in habitats such as bogs and wetlands. Pinguicula species vary in appearance, with some displaying colorful flowers that attract pollinators.
