Coenagrion scitulum (Dainty Bluet) is a common species in southern Europe which has been expanding its range to the north in recent decades. It’s one of the smallest blue-and-black species in Europe. You’ll typically find Dainty Bluets on shallow, sun-warmed standing (or rarely slow-flowing) habitats covered with mats of floating hydrophytes like hornworts. Within its range suitable habitats can often be found in quarries and on cattle ponds.
