Abstract: Spatial Use of the Owly Sulphur north of the Alps – Consequences for species protection Isolation of habitats remains one of the most severe threats to biodiversity, and it is vital to enable exchange among habitat islands by creating suitable stepping stones or connecting habitat corridors. The Owly Sulfur Libelloides coccajus has been heavily affected by isolation north of the Alps since it depends on dry and warm open forests and on grasslands which should not be cut before early August. The study investigated flying habits of this protected species in order to elucidate both its core habitat and adjacent areas used for hunting and mating, with special regard to obstacles. The results revealed that wind protection seems to be one of the prime requirements for L. coccajus, whereas land use and thus vegetation type play a minor role, at least as far as hunting is concerned. For instance, L. coccajus was frequently observed to fly and hunt above corn fields and other crops. Apparently, neither hedge rows nor crop fields seem to seriously hamper the dispersal of L. coccajus. This finding is very important for designing and creating effective stepping stones and connecting corridors between the remaining L. coccajus populations.
