Gall midge galls on beech leaf. Close-up of two galls (round) on the upperside of a beech (Fagus sp.) leaf. These galls are caused by the gall midge (Mikiola fagi),which lays its eggs inside the leaf's tissue. When they hatch,the larvae secrete chemicals that cause the leaf's tissue to form a protective 'bubble' (gall) around them | |
