Gall wasps are small insects belonging to the family Cynipidae. They are known for their unique ability to induce the formation of galls, which are abnormal growths on plants, particularly on oak trees. These galls provide a protective environment for the wasp larvae to develop. The life cycle of gall wasps typically involves laying eggs inside plant tissues. The plant responds to the wasp's presence by forming a gall, which serves as both food and shelter for the developing larvae. This fascinating interaction between gall wasps and plants showcases the complex relationships in nature.
