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

Cheilosia antiqua (Meigen, 1822)

Biology: The larvae feed in the rootstocks of Primula, where they hollow out cavities in the thickened stem bases, often killing the plants. Found in woodland clearings and tracksides and unimproved pastures where the foodplants grow. Adults are generally found along woodland rides or edges, and along old hedges, where they fly low-down amongst the vegetation

Distribution: Records are thinly scattered from throughout Britain. Some records for C. antiqua may actually refer to Melanogaster hirtella, male specimens of which are not infrequently mistaken for this species

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

CHEILOSIA PUBERA (Zetterstedt) NOTABLE

DISTRIBUTION Records widely dispersed in England and Scotland as far north as the Isle of Mull.

HABITAT Fens, fen carr, wet pastures, lake margin marshes, possibly requiring base rich conditions.

ECOLOGY Larvae probably phytophagous, though host plant unknown and not easily predicted. Adults recorded from early May to late June and may be found sunbathing on foliage or visiting buttercups and marsh marigold.

STATUS About 15 known post 1960 sites, mainly from northern England (Yorkshire, Cumberland and Northumberland), Scotland (not uncommon on Mull, also recorded from Berwickshire and Midlothian) and an isolated site at Leckford, Hampshire (1947 & 1976). Status revised from RDB3 (Shirt 1987).

THREAT Drainage of wetlands for agricultural improvement and intensive forestry; pollution such as agricultural run-off and scrub invasion of wetlands through a fall in water level.

MANAGEMENT Maintain a stable water level at sites; a mosaic of vegetation types (including open rides and clearings in woods) should sustain the as yet unknown larval requirement.
