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

Cheilosia carbonaria Egger, 1860

Biology: The larvae of this species remain unknown. Adults are most frequently found along woodland rides and edges, usually on well-drained and calcareous soils. They fly low along tacksides, woodland edges and large hedgerows and visit a range of white umbels and yellow composites

Distribution: An uncommon species found mainly in well-wooded areas of central-southern England from Sussex to Devon, but with a few isolated records from as far north as Derbyshire. Although Stubbs (1982) lists this as a ‘good’ primary woodland indicator, it has proved not to be confined to ancient woodlands

Datasheet from the Review of Scarce and Threatened Diptera, Falk (1991).

CHEILOSIA CARBONARIA (Egger) NOTABLE

DISTRIBUTION A clumped distribution in southern England with records extending as far north as Derbyshire.

HABITAT Mostly associated with rides, clearings and edges of old broadleaved woodland.

ECOLOGY Larvae phytophagous though the host plant is unknown. Most likely to be composites such as thistles Cirsium and Carduus. Adults recorded from April to August, usually found feeding on umbelliferous flowers. The flight period suggests that this species has two broods.

STATUS A scarce and very restricted species with about 15 known post 1960 sites but possibly under recorded to some extent through its resemblance to commoner species such as C. vernalis. Status revised from RDB3 (Shirt 1987).

THREAT Clearance of old woodland for agriculture or intensive forestry. Shading out of rides and clearings within.

MANAGEMENT Maintain rides and clearings in an open condition to encourage a rich and varied flora and associated insects such as this species.
