Using a vulnerable woodland species, P. mnemosyne, we carried out a detailed marking campaign designed to eliminate biases towards individual sexes on marking. We then estimated the numbers of males and females; compared details of mobility between males and females; and found out if effect of weather differ between sexes. The estimated population size was 4000 adults, with a male : female sex ratio of 1.5–1.6. Both daily and average catchability were higher for males, while the residence values (i.e., survival) were higher for females. Migration parameters were similar for the sexes. Although weather affected the sexes differently, males still retained lower survival. The surplus of adult males in the studied population of P. mnemosyne was real, not caused by increased male survival or a difference in mobility.
