Question of the Week – Fourlined Plant Bug

Question of the Week – Fourlined Plant Bug

This week, the question was: What is this critter on this sunflower leaf?

This is a fourlined plant bug. This small insect is commonly seen in the spring and usually disappears by early summer. It is a relatively minor pest of numerous plants including brassicas, cucurbits, beans, and members of the Solanaceae family, though it seems to have a preference for members of the mint and sunflower families. Fourlined plant bugs have piercing-sucking mouthparts and create distinct feeding damage, which can be seen on some of the leaves in the photo above. More information about the fourlined plant bug can be found here.
