The Hessian fly does more damage to the wheat crop than all other insects combined, and probably ranks next to the chinch bug as the second worst insect enemy of the farmer. It was probably introduced into this countr\- by the Hessian troops in the War of the Revolution. In autumn the insect lays its eggs in the leaves of the wheat. These hatch into the lanae, which move dovMi into the crown of the plant, where they pass the winter. There they cause on the plant a slight gall formation, which injures or kills the plant. In the spring adult flies emerge and lay eggs. The larvae that hatch feed in the lower joints of the growing w^heat and prevent its proper growth. These lar\ae ^^ pupate and remain asFig. i6q.
