Gall wasps are tiny insects that are known for their ability to create galls on plants, which are abnormal growths that can cause damage to the host. These insects are also referred to as gallflies or cynipids. Other synonyms for gall wasps include oak apple wasps, rose bedeguar gall wasps, and grape phylloxera gall wasps. Gall wasps are attracted to specific plant species, and their presence can have a significant impact on plant growth and development. While these insects can cause harm to crops and landscapes, they are an important part of the ecosystem and have been studied extensively by scientists.
