The adults do no damage to living plants. The larvae, called wireworms due to their narrow, shiny, jointed appearance, spend most of their time in rotted stumps and logs. The larvae of some other click beetle species, including Limonius spp. and Agriotes spp., are considered pests because they feed on the roots of lawns, vegetables, and flowers. But the larvae of eyed click beetles tend to leave gardens and lawns alone, preferring instead to prey on the larvae of wood borers (pests that you definitely don't want in your yard). So the next time you see one of these guys, rest assured that it won't harm you or your plants, and let it go along on its merry way.
