摘要:Since 1923 to 2006(84 years), many insect fossils have been found and reported from Shuinan Formation in Laiyang basin. The researchers included Grabau, Ping Zhi, Hong Youchong, Zhang Junfeng, Wang Wenli, Yang Jikun, et al. The insect group from Shuinan Formation consist of terrestrial and aquatic insects, most of it is terrestrial insects. Its represent-ative species are: Chironomapteria gregaria, Mesolygaeus laiyangensis, and Coptoclava longipoda. By contrast, the era of Shuinan Formation is Early Cretaceous Epoch. According to the statistics, the insect fossils have 12 orders, 67 families, 131 genera and 161 species, thereinto, 5 genera's familiae incertae sedis. The dominant insects were Diptera, Coleoptera and Hymenoptera, which were obviously different from the present ones. There are four levels of food chain among insects: plants (producers) - primary consumers - level two predators - level three predators. According to fossil insects and the other biology fossils from Shuinan Formation, this paper analyzes the ecological characteristics of the ancient Laiyang basin at the time. It provides the foundation for the protection of insect fossils production in Laiyang basin and the construction of the Cretaceous National Geopark in Laiyang City Shandong Province.
