物种的正确鉴定是系统学研究的基础，形态学特征因直观易于操作而作为分类特征在物种鉴定中起到重要的作用。目前，蝴蝶的分类鉴定多依据成虫的形态特征，致使翅面斑纹相似，外生殖器差异不明显的类群分类非常混乱，环蛱蝶属Neptis就是这样一个类群。本项目以所有环蛱蝶属的种及亚种为研究对象，通过野外采集幼虫或越冬卵，或诱导成虫产卵等手段，饲养获取全部虫态的特征，结合DNA分子数据，完成分类单元的修订，剖析全虫态的进化特征，运用现代支序系统学的研究方法，重建环蛱蝶属的种间系统发育关系，提出反映该类昆虫的自然历史分类系统。其结果是开展环蛱蝶演化及生物地理学研究的前提，并有利于蝴蝶幼虫发生期的快速、准确鉴定。

Identification of a species is the base for systematic study, morphological characters play an important role in identification of species due to its concreate and feasible operation in practice. However, charactors adopted in the current study of butterflies are mainly focused on adults, which lead to misidentification among the species that share similar wing pattern and genitalic features as in the genus Neptis.The project aims to study specie and subspecies of the genus Neptis. The methodology include the field surveys on adult, getting the eggs from female artificially and collecting caterpillors or eggs in wintering season, so as to gather the characters from all the developing stages including egg, larva, pupa and adult through the breeding to make revision of the genus, as well as the DNA data together to explore phylogeny of the genus by using of modern cladistic rules. The result will be helpfuf for the further study on evolution and biogeography, as well as for quick identification of Neptis speies at larval stage.
