Neurothemis terminata is a species of order Odonata found to be distributed in the Philippine archipelago and the rest of the tropical countries. Dragonflies were considered as ecological indicators since their presence indicates that water is fresh. Dragonflies are important in diminishing diseases spread by mosquitoes since they feed on them. Male and female N. terminata were determined based on the colors they exhibit but in terms of morphology it is very difficult to classify them due to their great similarities in structure. This study aims to find morphological variations in the wings of N. terminata. A total of 60 specimens collected 30 males and 30 females and were prepared in the slide then photographed uniformly using Vejo USB microscope. Homologous morphological structures between all specimens were picked out around the outline of the wings. Raw data were then examined using Relative Warp analysis processed by package software of TPS version 2. Results of the analysis show that most of the morphological differences in shape and size occur in the distal portion of the wings and also it suggest that female hindwings are wider than male hindwings. Discriminant Analysis revealed that morphological variations in the hindwings of N. terminata is significant concluding that male and female hindwings greatly differs in terms of shape and size.</span></em></p>
