Brachythemis contaminata

As for tying up loose ends, what about this most common of highly tolerant species? Brachythemis contaminata certainly is not a good indicator of water quality, or to the contrary, it is almost an indicator of low water quality, occurring in places where even rats cannot survive, making you wonder what they actually live off. Then again, mosquitoes thrive anywhere too. Its name goes well with its general surroundings. Interestingly, the study by Do Manh Cuong of the distribution of dragonflies in Vietnam, shows it as only known from 4 provinces. This is a clear indicator of the lack of data from Vietnam, not, sadly, of the fantastic state in most waterbodies are in. It is an easy to recognize species, at least the male, and can be found abundantly along low quality water bodies, where they sit on rubbish, twigs, concrete blocks, anything, along the water's edge or on anything protruding from the surface, like floating dead animals. It is certainly not that I do not like this species, I do, I just hate the sight of its surroundings most of the times.
