Caption
Recently restored grasslands (top row) are visited mostly by flies and hoverflies that are generalists and thus often carry pollen from one plant to flowers of a different species (from left to right: Syrphus torvus on Galium verum, Eristalis tenax on Thalictrum minus, Cheilosia japonica on Barbarea vulgaris, Prosena siberite on Eupatorium glehnii). On old grasslands (bottom row), on the other hand, pollinators are to a larger extent bees and butterflies that specialize in one species at a time, thus guaranteeing that the pollen is transferred to the right plant species (from left to right: Bombus diversus on Prunella vulgaris, Minois dryas on Cirsium oligophyllum, Megachile lagopoda furukawai on Platycodon grandiflorus, Inachis io on Scabiosa japonica).
