Field observation

For the plants, we placed four 1 × 1 m plots along each transect, separated by a distance of 50 m. In every plot, we recorded the presence or absence of all plant species from a pre-defined list of 169 species, all of which are frequently occurring in various types of grassland habitat in the study region. Walking slowly along the same transects, we identified and counted all butterflies and burnet moths (Zygaenidae; from here on included in ‘butterflies’) within 2.5 m to each side and 5 m to the front of the observer. We surveyed bumblebees along the same transects but within 1 m to each side and to the front. We caught and identified individuals in the field if possible or collected and identified them in the laboratory.
