Stag beetle behaviour and gender

All together, we already have data from more than 400 transect walks so we thought it would be a nice idea to look a bit closer to what kind of observations you have been entering. From the 444 transect walks analysed only 232 had stag beetle observations (so 52%). Regarding behaviour, it is clear that copulating and dead animals are a strong minority. Only during 6% of the transect walks with observations copulating was observed. Dead animals are found in 14% of the transect walks. So the majority of observations refer to flying and non-flying individuals. About 67% of the walks with observations have flying beetles and in 50% they are even the majority of the observations. Non-flying beetles are present at 48% of the transect walks and represent the majority of observations in 27% of the transect walks.
Concerning gender, 50% of the transects with observations have female observations, meaning that they are also lacking in half of the observations. Only in 18% of the cases, female observations are dominant. For males, 79% of the observations include males with 67% where they are dominant.
