Local name: rödhornslökblomfluga

UnknownENEUENEU

Overview

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

Eumerus ruficornis faces severe population decline primarily due to habitat loss from agricultural intensification and urbanization across its limited European range. The species' specialized larval requirements for specific plant hosts make it particularly vulnerable to changes in vegetation composition and management practices. Climate change poses an additional threat by altering the phenology of both the fly and its host plants, potentially disrupting critical breeding cycles.

Threat summary

Habitat

This hoverfly species inhabits flower-rich grasslands, meadows, and woodland edges across parts of Europe, where adults feed on nectar from various flowering plants. The larvae develop in the stems and roots of specific umbelliferous plants, making the species dependent on diverse, unmanaged grassland ecosystems.
