| Oak galls are also called Apple Galls. They hang from a leaf stem much like an apple. They are rounded growths filled with a spongy mass that indicate an insect presence. A single wasp larva is located in the hard seed-like center. The gall grows and at some point, the wasp emerges. Oak galls are high in tannic acid and are used by some Chinese medicine practitioners. They can be found profusely where Oaks grow and don't usually harm the tree. |
