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

Pipiza austriaca Meigen, 1822

Biology: The larvae of this genus are aphidophagous, appearing to favour aphids which secrete a waxy flocculence (woolly aphids). They have also been reared on Cavariella aphids on Heracleum sphondylium.Adults are usually found resting on vegetation along woodland margins, although they occasionally visit flowers

Distribution: Widespread but local in southern England, apparently becoming scarcer to the west and north, with records extending into southern Scotland

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

PIPIZA LUGUBRIS (Fabricius) NOTABLE

DISTRIBUTION Scattered records in England as far north as Durham and with an old record for North Wales.

HABITAT Uncertain though possibly heathland areas adjacent to old broadleaved woodland.

ECOLOGY Larvae probably aphidophagous though details unknown. Adults recorded from May to October.

STATUS About 10 known post 1960 sites, with many old records likely to be incorrect and applying to the common P. noctiluca.

THREAT Clearance of woodland and heathland for agricultural or intensive forestry.

MANAGEMENT Maintain open rides and clearings in woods; ensure a mosaic of vegetation types on heathland, using traditional management techniques to prevent scrub invasion.
