The butterworts are a group of carnivorous plants comprising the genus Pinguicula. Members of this genus use sticky, glandular leaves to lure, trap, and digest insects in order to supplement the poor mineral nutrition they obtain from the environments. Of the roughly 80 currently known species, 12 are native to Europe, 9 to North America, and some in northern Asia. The largest number of species is in South and Central America.
