| Description | Faecal pellets were collected under one maternity colony of each of E. serotinus and E. nilssonii. Nematoceran Diptera, mainly Chironomidae, were the most frequent food items in both species. Coleoptera, Lepidoptera, Heteroptera (Corixidae, Lygaeidae) and Hymenoptera (Formicoidea, Ichneumonidae) were common in E.s.; Lepidoptera, Heteroptera (Miridae), Aphidomorpha, Psyllomorpha and brachyceran Diptera were common in E.n. Although both species prefer aerial hawking and hunt for swarming insects if available, comparison of their diets and comparison with data of other authors revealed differences in foraging and diet between and within each of the species studied. |
