Somatochlora arctica

Somatochlora arctica is widely distributed across the northern regions of Eurasia, from Scandinavia and the British Isles through Siberia. It inhabits boreal forests, moorlands, and acidic bog habitats, particularly small pools and seepages within peatland ecosystems. It is considered locally common in suitable habitat but is rare or absent from southern and lowland areas.

The northern emerald breeds in acidic, nutrient-poor water bodies such as bog pools, peat cuttings, and small forest ponds within Sphagnum-dominated wetlands. These habitats are typically found in boreal and subarctic regions where peat accumulation creates the specific chemical conditions the species requires. Larval development takes place underwater in these pools before the adults emerge.

Somatochlora arctica is a medium-sized dragonfly in the family Corduliidae with a dark metallic green or bronze body typical of emerald dragonflies. It has relatively clear wings and bright green eyes, and can be distinguished from similar Somatochlora species by details of its abdominal markings and the shape of its anal appendages. Males patrol territories over bog pools, making them identifiable by both sight and behavior.

The conservation status of Somatochlora arctica varies across its range. While it is not globally threatened due to its wide distribution across northern Eurasia, it is considered locally rare or declining in parts of Western Europe where peatland drainage and habitat degradation have reduced suitable breeding sites. In countries like Germany and the United Kingdom, its bog habitats receive specific conservation protection.
