Overview
Eristalis oestracea, the orange-tailed drone fly, is a species of hoverfly native to Europe and North America. In Europe it is found in bogs, moors, and coastal dunes. It nectars on white flowers in the carrot family (Apiaceae) and yellow flowers in the aster family (Asteraceae). It is very poorly known in North America. E. oestracea measures 14-15 mm in length.
Bremse-dyndflue (Eristalis oestracea) faces significant threats from habitat degradation and loss of wetland environments essential for its larval development. Agricultural intensification and urban development have reduced the availability of suitable breeding sites, while pollution and climate change further impact the aquatic habitats this hoverfly depends on.
Habitat
This hoverfly species inhabits wetland margins, shallow pools, and slow-moving water bodies where organic matter accumulates, providing suitable conditions for its aquatic larvae. Adults are typically found in adjacent grasslands, meadows, and woodland edges where they feed on nectar from various flowering plants.
