In order to truly elucidate their natural history and the development trends, we need to cover more species, including the extinct and extant species. In general, fossils sometimes appear to be necessary since extinct species usually have the so-called transitional states, which play important roles in their early evolution. It is well known that the Early Cretaceous Yixian Formation and the Middle Jurassic Jiulongshan Formations of Northeastern China have yielded well- preserved insects, including sawflies and some woodwasps. The great morphological diversity of symphytan fbssils, especially those transitional character states, will make significant contributions to our understanding of the developmental trends of this basal group, as well as the evolution of hymenopterans.展开更多
