Eupeodes nitens (Zetterstedt, 1843)
Syrphus nitens Zetterstedt in Coe (1953), Metasyrphus nitens (Zetterstedt) in Stubbs & Falk (1983).
Biology & ecology:
The larva is predaceous upon aphids on shrubs, with reports of associations with aphids on Black Currant Ribes nigrum, Elderberry Sambucus nigra and Spindle Euonymus europaeus.
The majority of records are southern or western and are largely confined to England. Obvious centres of population lie in Dorset, Hampshire and Surrey with a further concentration of records along the Severn valley and the Welsh Marches. The most northerly records are from southern Cumbria and County Durham.
Status & conservation:
The frequency of occurrence is very variable with a very slight (but not significant) downward trend.
