Margrietboorvlieg

Oxyna nebulosa

Unknown

Overview

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

Oxyna nebulosa faces severe population declines primarily due to the loss and degradation of its specialized coastal dune habitats across northwestern Europe. Agricultural intensification and urban development have eliminated many historical breeding sites, while remaining populations are increasingly fragmented. Climate change poses additional pressure through altered precipitation patterns that affect the host plant communities this species depends upon for reproduction.

Threat summary

Habitat

This specialized fly inhabits coastal sand dunes and sandy grasslands along the North Sea and Atlantic coasts of Europe. It requires areas with specific host plants in the Asteraceae family, particularly in semi-natural dune systems with low to moderate vegetation cover.
