Using Geometric Morphometric Techniques to Analyze Wing Variation of Common Dragonflies
This study uses geometric morphometric techniques to analyze the wing morphological characteristics of four common species of dragonflies in Linhai,Zhejiang Province,and to discuss the variation regulation of wing shape and venation.The study also explores the phylogenetic relationships among the four species.The results of principal component analysis (PCA) show the fore and hind wings of the four species of dragonflies Deielia phaon and Crocothemis servilia have high similarity in the shape of fore and hind wings.However,Pantala flavescens species is significantly different from the other types of dragonflies.The main wing difference can be shown by the wing type mesh contour map,which includes the pterostigma,nodus,radius area,cubitus area,and anal area near the base of the wing.Clustering analysis provides further evidence for the morphological relationship among dragonflies.Based on clustering results,it is determined that D.phaon and C.servilia have the closest phylogenetic relationship.Meanwhile,P.flavescens has the farthest relationship with the other dragonflies.Trithemis aurora is very different in terms of its fore and hind wings.
