The four-lined plant bug, Poecilocapus lineatus which is easily identified by the four black strips running down its back, has a wide range of hosts including: fruits, vegetables, flowers, herbs, and cucurbits. The associated damage consists of spots that look similar to fungal disease spot and can be misidentified as such. Damage is inflicted by the bug's piercing-sucking mouthparts and is usually not severe enough to cause plant death.
The four-lined plant bug nymphs are a bright red to orange color with black dots on the abdomen. Later instars have black wing pads running ½ way down the abdomen with a yellow strip on each wing pad; they do not have actual wings however. Adults are usually a greenish-yellow color with four black strips running longitudinally down the wings. The head, antenna, and body are all black in color while the legs are yellow-green with black marks. Both nymphs and adults have piercing-sucking mouthparts.
