The Mark-Release-Recapture (MRR) method is a widely used method to estimate populations of different organisms in a given environment throughout the field of biology. The biological material was collected during the year 2023. This study uses the MRR (Mark – Release – Recapture) method to assess the population, distribution, territoriality and behavior of the study species Pseudochazara Tisiphone Brown, 1980 in the area of Drenova. The MRR method involves marking individuals, releasing them into the environment, and then recapturing them again to calculate the number of marked recaptures. Based on the number of marked individuals that are recaptured, we determine the total number of individuals in a population. This method provides a sustainable and effective way to monitor and study natural populations in their environments. During this year we managed to catch 32 species of this type, of which we found 21 females (65.6%) and 11 males (34.3%) based on behavioral differences. The captured individuals are tagged and released, according to the MRR methodology. By analyzing the marked species, it turns out that we have 6 individuals or (18.7%) of the Pseudochazara Tisiphone species found again. Of these 6 individuals, 4 individuals are female (12.5%) and 2 are males (6.25%). This recurrence rate is low. From the analysis of the days according to the months, in which we met and re-met more often individuals of Pseudochazara Tisiphone, it turns out that the frequency of meeting this type results more at the end of summer.
