Abstract

The behavior of Enallagma vansomereni was investigated using mark-recapture techniques across a network of six stations. This study was conducted extensively in Qena Governorate, focusing on the ecology and evolution of this species. While mark-release-recapture methods are feasible for some animals, they present significant challenges for small, fast-moving species like insects. These challenges include low recapture rates, which can introduce biases in estimates of demographic parameters and hinder effective analysis and management of wild populations. In this study, the author utilized mark-recapture methods to examine the daily movement and survival probability of Enallagma vansomereni. A total of 2635 individuals (1770 males and 865 females) were marked and measured during the study. Of these, 1476 individuals (56.00%, comprising 1202 males and 274 females) were successfully recaptured. The daily movements of Enallagma vansomereni indicated that 1160 individuals were marked, with 1050 individuals observed moving either within or among the stations.
