Answer
(a) please see the attached free body diagram
(b) During the jump, the leaf hopper is accelerating upward, therefore the net force points in the upward direction. Therefore, the normal force (the force of the ground) is greater in magnitude than the force of gravity. Note that the oval shape in the free body diagram represents the leaf hopper.
