|Remaining occurrences||At Lake Constance, in the Black Forest, in Lower Saxony|

|Habitat||Sour brooks and moors|

The small red damsfly, is a very conspicuous dragonfly – one of the few red dragonfly species in Europe. It grows only 3.5 cm tall and is atypically location-loyal for dragonflies. It moves a maximum of 300 m away from its waters. It preys on mosquitoes and gnats up to its own size and weight.
It is a pointer species for acidic, slowly flowing, not shaded streams and stagnant waters, since it only occurs there. The last proven site in Rhineland-Palatinate in 1980 was destroyed by the construction of a highway bridge pier. Also at all other suitable sites the species could not be detected despite intensive search.
