A small, delicate damselfly species endemic to parts of western Europe, characterized by distinctive blue and black coloration in males. This species belongs to the Coenagrion genus, a group of slender, agile damselflies found in freshwater habitats.
Typically inhabits shallow, vegetated freshwater environments including small ponds, slow-moving streams, wetlands, and bog pools with abundant aquatic vegetation, predominantly in Ireland, United Kingdom, and parts of northern Europe.
Critical for aquatic ecosystem balance, serving as both predator and prey. Adults consume small flying insects, while larvae are important in aquatic food webs and act as bioindicators of water quality and environmental health.
