Mark-recapture (MR) study was performed on three forest defoliating Geometrid moth species in the Kőfejtő Forest between Sopron and Kópháza. In total, we marked 1235 specimens; the recapture rate differed between the study species. The highest superpopulation size was estimated for E. defoliaria, followed by E. aurantiaria and C. pennaria. The daily population sizes were also estimated; it shows different swarming dynamic for each species. The movements of recaptured specimens even were investigated. In spite of the weak flying capability, we detected relative long movements for E. defoliaria and E. aurantiaria. We conclude that MR study show a more precise population size than generally used light trapping. However, we have only a few information about MR study on moth species; it requires further investigations and clarification.
