The first part of the poster shows images of Aeshna juncea taken with a fl at scanner and a conventional photo camera in order to demonstrate advantages and disadvantages of these two methods for displaying dragonflies. Sanned images are difficult to take, but good to reproduce the natural colours and detailed structures. Contrary, conventional photography is much more ad vantegous for taking images of individuals in their natural environment. A combination of both methods may increase the illustrative value of an image. The second part of the poster represents some observations of the reproductive behavior of Aeshna juncea.
