Oblong-leaved sundew is a insect-eating plant and is legally protected in the Netherlands. The leaves are covered with long, sticky hairs which catch insects. The majority of its victims are mosquitos and small flies. Oblong-leaved sundew has slightly elongated leaves that stand diagonally straight out of the ground. It has an intenser brown-red color than round-leaved sundew. In fact, if placed on a pile of sturdy white paper, it leaves a brown coloring which can penetrate 4 layers!
