Sitona lineatus, commonly known as the pea leaf weevil, is a small insect belonging to the family Curculionidae. It is typically found in Europe and North America. The adult weevils are about 4-5 mm in length and have a distinctive elongated body shape with a dark brown coloration. They feed on the leaves of leguminous plants, particularly peas and beans, causing damage to the foliage and reducing crop yields.
