Eumerus grandis
Local name: rödsidig lökblomfluga
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Eumerus grandis 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 bulb-feeding environments make it particularly vulnerable to changes in land management practices. Climate change poses an additional threat by altering the phenology of its host plants and disrupting synchronized breeding cycles.
Habitat
This specialized hoverfly inhabits areas with wild bulbous plants, particularly in semi-natural grasslands, meadows, and woodland edges where its larvae develop in bulbs of Allium and related species. The species requires a mosaic of flowering plants for adult nectar feeding and specific bulb-rich microsites for reproduction.
