In this study geometric morphometric analysis of some Hymenoptera species was undertaken. The aim was to discriminate maxillosus, flavipennis and pruinosus species of the Sphex genus from each other by applying geometric morphometric methods. Species were identified by making use of the morphometric wing measurement data from different families in Hymenoptera group. In this study, the possibilities of applying morphometrics methods on taxonomy studies were explored. oreover, thesuccess rates of both methods were compared using geometric morphometry techniques.
