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

 Meligramma euchromum (Kowarz, 1885) Syrphus euchromus Kowarz in Coe (1953), Epistrophe euchroma (Kowarz) in Stubbs & Falk (1983)

Biology: The larvae are aphidophagous, and mainly associated with trees (particularly fruit trees) and shrubs. Adults are usually found in or around woodland or scrub, and are most often seen basking on sunlit foliage, especially Acer pseudoplatanus and Aesculus hippocastanum leaves. A specimen was reared from a puparium found in a suburban garden in Surrey (G. Collins, pers. comm.)

Distribution: A rare species with few records, mainly from the south-east, but extending north to north-west England. Although possibly overlooked amongst other black and yellow species, this appears to be a genuinely elusive hoverfly and it is possible that adults spend much of their time out of reach in the canopy

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

EPISTROPHE EUCHROMA (Kowarz) RARE

DISTRIBUTION Scattered records mainly from southern England but extending to Lancashire and an isolated record from Aviemore in Scotland.

HABITAT Broadleaved woodland, adults usually found in rides, clearings and wood edges. There seems to be a preference for old woods.

ECOLOGY Larvae aphidophagous and abroad have been recorded feeding upon aphids on Euonymus europaeus and on cherry Prunus avium. Adults recorded from April to June and have been found on the blossom of sloe and the flowers of wood spurge Euphorbia amygdaloides.

STATUS A very scarce, possibly declining species with seven known post 1960 sites in contrast to a good number of older ones. Occurence is rather unpredictable and apart from a few sites such as in the New Forest there seems to be little attachment to individual sites, suggesting a mobile and adventive species. Even at sites where formerly common, it seems to have declined and recent records usually refer to single individuals.

THREAT Clearance of woodland for agriculture and intensive forestry, and especially of the sloe at woodland edges and in rides and clearings. The shading out of rides and clearings within woods.

MANAGEMENT Maintain the presence of sloe in rides, clearings and woodland edges. Prevent the scrubbing over of rides and clearings, using rotational scrub clearance if necessary.
