''Coenagrion mercuriale'', the southern damselfly, is a species of damselfly in the family Coenagrionidae. It is found in Algeria, Austria, Belgium, France, Germany, Italy, Liechtenstein, Luxembourg, Morocco, the Netherlands, Portugal, Slovakia, Slovenia, Spain, Switzerland, Tunisia, and the United Kingdom. Its natural habitats are rivers and freshwater springs. It is threatened by habitat loss. The specific part of the scientific name, ''mercuriale'', is because of the distinctive markings on the second segment of the abdomen that resembles the astrological symbol for the planet Mercury - ☿. This also gives the species an alternative common name of mercury bluet.〔(【引用サイトリンク】url=http://www.dragonflypix.com/checklist.html )〕 ==Habitat==
They require areas of open vegetation, mixed with slow flowing water in which to lay their eggs. The larvae spend 2 years underwater before emerging as damselflies.
