Species Profile
Eumerus sabulonum is a species of hoverfly, from the family Syrphidae in the order Diptera.
The duinbollenzweefvlieg faces significant threats from habitat loss and degradation of its specialized coastal dune ecosystems. Climate change and sea level rise pose additional risks to these narrow coastal habitats, while increased human development and recreational pressure in coastal areas further fragment and degrade suitable breeding sites.
Key Facts
Habitat & Distribution
Coastal sand dunes and sandy areas near the sea, particularly areas with bulbous plants and flowering vegetation that serve as breeding and feeding sites. The species is closely associated with specific dune plant communities and requires undisturbed sandy substrates for larval development.
Threats
Climate change and sea level rise
Coastal habitat loss and fragmentation
Human development in coastal areas
Loss of host plant populations
Recreational pressure and trampling
