Oak Apple Gall Information
So what are oak galls? Oak apple galls appear in oak trees, most often black, scarlet, and red oaks. They get their common name from the fact that they are round, like small apples, and hang in the trees.
Oak apple gall information tells us that galls are formed when a female oak apple gall wasp lays eggs in the central vein on an oak leaves. When the larvae hatch, chemical and hormone interaction between the wasp eggs and the oak causes the tree to grow the round gall.
Galls are essential to developing oak apple gall wasps. The gall provides a safe home as well as food for the young wasps. Each gall contains only one young wasp.
If the galls you see are green with brown spots, they are still forming. At this stage, the galls feel a little rubbery. The galls get bigger as the larvae get bigger. When the galls dry out, the oak apple gall wasps fly from small holes in the galls.
