Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Nordisk mosesvirreflue faces severe habitat degradation due to drainage and modification of its specialized bog and wetland environments across Scandinavia. Climate change poses an additional threat by altering the hydrological conditions essential for maintaining the moss-rich microhabitats this hoverfly depends on for breeding. Agricultural intensification and peat extraction in surrounding areas further fragment and degrade the pristine wetland ecosystems required for its survival.

Threat summary

Habitat

This specialized hoverfly inhabits pristine Sphagnum bogs and moss-rich wetlands across northern Scandinavia, particularly areas with dense moss carpets and stable water levels. The species requires undisturbed bog ecosystems with specific microhabitat conditions including moss-dominated ground cover and associated flowering plants that provide nectar sources.
