Pinguicula lutea has essentially the same vegetative structure as P. caerulea, with the basal rosette of widely elliptical and sticky leaves being about 2-3 inches across. Thus, you must see it in bloom to tell the two apart. Read more at Vascular Plants of North Carolina.
When an insect becomes stuck on a Buttersort leaf's sticky mucilage, the edge of the leaf slowly rolls over. When the insect is digested, the leaf edges unroll. Read more at the Botanical Society of America.
