Overview

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

The zomerse glimmer faces significant pressure from wetland habitat degradation and loss across its European range. Agricultural intensification and urban development have reduced the availability of suitable bog and fen environments where this hoverfly depends on specific plant communities for breeding. Climate change poses an additional threat by altering the hydrology of these sensitive wetland ecosystems, potentially disrupting the delicate moisture conditions required for larval development.

Threat summary

Habitat

This specialized hoverfly inhabits pristine wetland environments including sphagnum bogs, calcareous fens, and marshy meadows across northern and central Europe. The species requires undisturbed areas with specific moisture regimes and diverse flowering plant communities that support both adult feeding and larval development in organic-rich substrates.
