The insect pictured preys on other insects and benefits people. This group is characterized by the elongated, narrow head with the three-segmented beak folded back under the head.
Most predaceous hemiptera (true bugs) have front legs modified for grasping prey. Probably the most distinguishing character of hemiptera is the wing structure, which generally has the front wings overlapping and lying flat on the back over the membranous hind wings.
