Abstract Heidelibellen laichen im Tandemflug über dicht bewachsenem Flachwasser ab. Das voranfliegende Männchen bremst abrupt jeweils dicht über den Eiablageplätzen und biegt den Hinterleib nach vorn, so daß das Weibchen nach vorn unten geschleudert wird. Der Hinterleib steht senkrecht, die Hinterleibsspitze berührt das Substrat. Das Flugverhalten der Weibchen kann dabei völlig passiv sein. Freilandaufnahmen mit Zeitdehnung.
The egg-laying of the Ruddy Sympetrum (S. sanguineum) in tandem-position is shown. By means of 500 f/s details of the male-female cooperation and the movements of the wings are visible. A male is carrying a female with only three wings.
