Cynipidae, commonly known as gall wasps, are a family of small insects belonging to the order Hymenoptera. They are known for their unique ability to induce the formation of galls on various plants, particularly oaks. These galls serve as protective structures for their larvae, providing both nourishment and shelter during development. There are over 1,000 species of gall wasps, each typically associated with specific host plants. The life cycle of Cynipidae involves laying eggs in plant tissues, which triggers the plant to form a gall. This fascinating interaction highlights the complex relationships between insects and plants in ecosystems.
