Overview

Eumerus sogdianus is a species of Hoverfly, from the family Syrphidae, in the order Diptera.

The duistere bollenzweefvlieg faces significant threats from habitat loss and degradation of its specialized environments. Agricultural intensification and urban development have reduced the availability of suitable breeding sites and host plants essential for this hoverfly's lifecycle. Climate change may further impact the species by altering the distribution and phenology of its preferred habitat conditions.

Threat summary

Habitat

This hoverfly species inhabits open grasslands, meadows, and agricultural margins where bulbous plants and other herbaceous vegetation provide breeding substrates. It is typically found in areas with scattered flowering plants that serve as nectar sources for adults, often in semi-natural landscapes with mixed land use.
