Description about Gall makers:
Gall makers arrive in silence, like old buccaneers, but without eye patches or shoulder parrots. They also confiscate their rewards quickly and effectively, putting them to work doing their bidding with eye-catching results. Gall-producing insects include a variety of wasps, flies, and a few aphids and mites. Instead of transporting its loot to a secluded cove, the gall maker chemically hijacks a leaf bud or other spot on a tree to construct a casing of plant tissue that protects and nurtures the gall maker’s growing children. Over half of these fascinating critters are attracted to oak trees. Galls can develop on the leaves, bark, flowers, buds, or roots of plants. Except for some twig and stem galls, most growths do not affect healthy trees.
