There area a goodly number of dragonfly species, the males of which develop a powdery blue coating on various parts of their bodies, most notably the abdomen. Since the coating is called pruinosity after the bloom that develops on the skin of fruit, we have affectionately taken to referring to such species as prunes, for short.
This is just about the commonest prune of the set.
- black pterostigma
- generally greenish eyes
- mature ♂ – pruinose abdomen with black tip
- stockier build than the similar O. albistylum
