The present volume focuses on the Orange-spotted emerald Oxygastra cutisii - a slender, medium sized dragonfly with bright green eyes. The species was first described from Britain in 1834, but has become extinct in that country. Subsequently, the species was found in Germany between 1940 and 1943 on the river Sieg in Northrhine-Westfalia, and from where it later disappeared as a consequence of habitat destruction.

It was then not seen in Germany for decades and as a consequence the species was classified on the national red lists as "extinct". However in 1999 it was discovered by chance at the river Our, which forms the border between Germany and Luxembourg. As the species is listed in the Annexes II and IV of the EC Habitats' Directive, this newly-discovered population immediately recieved special attention by odonatologists and nature conservationists.

In addition, the governmental agencies were obliged to take special action to protect this population. The nearest populations are on the river Ourthe in Belgium, and at the river Meuse in France. This book is for conservationists, limnologists, landscape ecologists, landscape planners, as well as all dragonfly lovers.
