Bemerkungen/Beschreibung

In this study, diurnal Lepidoptera (butterflies),
which are ideal biological indicators, were recorded from the end of June to July 2025. The aim
was to investigate the influence of environmental factors on butterfly diversity and abundance
which may result in better management recommendations. Nectar-flower abundance and
vegetation height positively correlated with the number of individuals observed, but not the
number of species. Cloud coverage had no noticeable impact on recording success. I also
compared the local diversity and number of individuals between surveys in mid and high
summer and contrasted the gamma diversity of the two study years 2023 and 2025. The number
of species as well as the number of individuals were higher in midsummer. Species richness
and Shannon diversity of butterflies showed no significant difference between 2023 and 2025.
