Overview

Cheilosia bergenstammi is a widespread European species of hoverfly. Adults can be found in summer visiting ragwort flowers and this plant is also the larval hostplant.

Cheilosia bergenstammi faces severe population declines primarily due to habitat loss and degradation of its specialized wetland environments. The species is particularly vulnerable to drainage of peat bogs and marshlands, along with agricultural intensification that eliminates the specific plant communities it depends on for breeding and feeding.
