The Black Pennant wasn't known to occur here in Tuscany until we found and photographed it in July 2005. It's a very small dragonfly with a disproportionately large head. Selysiothemis nigra is a rare species in Europe with a very patchy distribution in Greece, the Balkans, Italy and Iberia.
Mature males are uniformly black in colour, although they do develop a whitish pruinescence on their thorax and abdomen. Immature males and females have a sandy-brown thorax and abdomen with extensive black markings. The species' most distinguishing features are the size of the wings (they're very large and broad for such a small dragonfly) and the shape of the pterostigma, which resembles an equals sign.

And then, if you'd like to get even closer, you can drag the ZoomBox from the top-left corner of that window across the photograph. Note that you may have to refresh the window manually (by pressing F5 on your keyboard) for the ZoomBox to display correctly.
