摘　　要：对新近发现于内蒙古和辽宁的多块脉翅目丽蛉科化石上的眼斑进行了描述,根据现生昆虫的拟态及现存脉翅目昆虫的行为特点,分析了丽蛉在进化上出现的拟态现象在当时的古生态环境中可能起到恐吓捕食者和引诱猎物的作用。眼斑拟态这种高度特化的生态适应现象使得多脉丽褐蛉在当时的古生态群落中占据了十分独特的生态位,同时也导致了其在中生代晚期环境突然变化中的灭绝。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. It is supposed that the eye-spot system is a kind of highly modified adaption of ecology which makes kalligrammatids get a very special ecological niche, and also lead to the extinction after the suddenly change of the environment in Mesozoic.
