Cheilosia carbonaria Egger, 1860Biology
The larva of this species is unknown. Adults are most frequently occur along woodland rides and edges, usually on well-drained and calcareous soils. They fly low along track sides, woodland edges and large hedgerows and visit a range of white umbels and yellow composites. Although Stubbs (1982) lists this as a "good" primary woodland indicator, it has proved not to be confined to ancient woodlands.Distribution
Most records are from well-wooded areas south of the Thames from Sussex to Devon. There are a few isolated records from as far north as South Lancashire.Status
