Species details

Cheilosia impressa Loew, 1840


The larva of this species remains unknown. Adults are found in damp situations such as carr woodland and wooded river-banks, where they visit white umbellifers, especially Hemlock Water Dropwort Oenanthe crocata, and a range of other flowers including yellow composites and buttercups Ranunculus sp. Males hover at moderate height in sheltered situations in clearings and glades.


Current records suggest that this species is mainly confined to England and Wales with the highest density of records in southern England. It occurs in a few lowland coastal localities in Scotland and one inland location in Perthshire.
