Galls
Swollen masses of abnormal plant tissue caused by fungi, bacteria or insects. There are many different kinds of galls primarily caused by wasp, fly, and aphid insects, they are usually more cosmetic than damaging. Insects “sting†a plant, which causes a growth that the insect uses as a home for its young. The gall serves as a shelter and food supply. Although unsightly, most galls are not considered very damaging. Natural control is biodiversity. Healthy plants seem to have fewer galls.
