OtherPix: 1: Side by Side

We made this photograph at a tiny little stream on the Greek Peloponnese in July 2010. This stream, only two feet wide in places and with a very extensive and dense vegetation along its banks, supported a wonderful array of species, the most numerous of which were the Greek and Balkan Goldenrings (Cordulegaster helladica and C. heros), the Eastern Spectre (Caliaeschna microstigma), and especially the Beautiful Demoiselle (Calopteryx virgo). And so within this very small and narrow habitat these species inevitably had to interact with each other, with the males of different species even sharing the few available perches overhanging the water. In this photograph a male Beautiful Demoiselle has decided to perch on top of a stick already occupied by a male Balkan Goldenring. Was it dangerous to do so? Is he keeping a watchful eye on his downstairs neighbour?
