Species account from Provisional atlas of British hoverflies, Ball & Morris, 2000.

Melanogaster hirtella Loew, 1843 Chrysogaster hirtella (Loew) in Stubbs & Falk (1983)

Biology: The larvae are aquatic, inhabiting mud adjacent to emergent plants such as Typha and Glyceria, but especially favouring Caltha palustris, usually at the edges of running water. They have modified hind spiracles which are used to gain access to the air spaces in the submerged parts of emergent plants. Found in marshes or near the margins of running water where there is lush emergent vegetation. Adults are usually swept from waterside vegetation or found visiting flowers, especially white umbels, Caltha, Iris, Menyanthes, Ranunculus, etc

Distribution: Widespread and common. According to Speight (1998) this is very much an Atlantic seaboard species which is quite scarce in central and southern Europe
