Eye-spots on several fossils discovered from Inner Mongolia and Liaoning Province are described, which are arranged to Kalligrammatidae, Neuroptera. Based on the research about mimicry of living insects and behavior of extant neuropteran, we suppose that mimics could play an important role for surviving of kalligrammatids in Mesozoic, might thunder against the predator or lure the prey.
