Dismembered prey samples, especially lepidopterans, were collected using fine nets underneath feeding perches around the summer roost of Eptesicus serotinus in the Čentice village (Central Bohemia). We evaluated the total number of moths, species composition and dominance of particular species in the diet of E. serotinus during the summer season.
In total, fragments of 299 individuals of lepidopterans were collected and identified. The most frequently culled parts collected under the feeding perches were Mamestra brassicae (40.5%), Odonestis pruni (11.7%) and Noctua pronuba (10.4%).
The most frequent families were Noctuidae (76.7%) and Nymphalidae (6.7%). The overwhelming majority of preyed lepidopterans were tympana moths of cultivated rural habitats.
More than 80% of the consumed moths were important agricultural pests.
