The Black One

This ominous-looking dragonfly is called black darter (Sympetrum danae):

^{Olympus Stylus 1s, 300mm, ISO400, f8, 1/500s}

I don't see these black ones often, and they are also harder to spot than their red cousin, the ruddy darter (Sympetrum sanguineum):

^{Olympus Stylus 1s, 300mm, ISO200, f5.6, 1/50s}
