gevlekte bollenzweefvlieg
Eumerus flavitarsis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
The gevlekte bollenzweefvlieg faces severe population declines primarily due to the intensification of bulb cultivation practices in the Netherlands, where pesticide use and soil treatments have eliminated many of its breeding sites. Urban development and infrastructure expansion have further fragmented its specialized dune and coastal grassland habitats. Climate change poses an additional threat through altered precipitation patterns that affect the moisture levels required for successful larval development in bulb fields.
Habitat
This specialized hoverfly inhabits coastal dunes, sandy grasslands, and traditional bulb cultivation areas in the Netherlands, particularly around Leiden and the broader Zuid-Holland region. The larvae develop in the bulbs and roots of various plants, making them dependent on both natural coastal vegetation and specific agricultural practices.
