The Atlas of the Hoverflies of Greece is the first of a kind within the Mediterranean region. It is the result of decades of research, many travels into the fascinating habitats of Greece (a biodiversity hotspot), visits to world museums, and many people’s passion for hoverflies. The Atlas is a concise presentation of all 418 hoverfly species for Greece known so far. The species are documented with photos and distribution GIS-maps and they are preceded by a general introduction on the hoverflies and Greek nature, and a generic key. The Atlas of the Hoverflies of Greece is a handbook for insect aficionados, students and teachers, everyone interested in nature, and managers and conservationists aiming at raising public awareness of a nature nowadays threatened more than ever.
