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

Scaeva selenitica (Meigen, 1822)

Biology: The larvae feed on aphids on Pinus and Picea. A puparium has been found under the bark of Picea. Records that make reference to habitat most frequently specify woodland (including both deciduous and coniferous), although open habitats, such as chalk grassland, are also mentioned. In the south of England this species is mainly associated with Pinus on heathland. Adults are often seen visiting flowers, such as white umbells, along woodland rides and edges and males hover in clearings

Distribution: Scarce but widely scattered. Whilst Stubbs & Falk (1983) state that it is at least a partial migrant, Falk (1991b) argues that it is resident. It is quite possible that a resident population receives reinforcement by migration from the Continent
