Pinguicula longifolia, commonly known as the long-leaved butterwort, is a perennial carnivorous subalpine plant of the Central Pyrenees, found on both sides of the border.

It catches its prey by using its modified leaves that lie on the ground and have “densely covered stalked glands that bear a droplet of sticky mucilage on its top.”[1] The need to capture arthropods is driven by the lack of nutrients present in the soil.

longifolia obtain their nutrition primarily from flying insects, mainly diptera, which replenished the carnivorous plant with nitrogen.

The endemicity of this subspecies in the Pyrenees is a problem as habitat destruction could lead to reduced space to propagate on.

The genus Pinguicula has been known to have many human uses, as they produce a strong bactericide, which prevents captured insects from rotting while digestion occurs.
