Melangyna barbifrons (Fallén, 1817)Nomenclature
Syrphus barbifrons Fallén in Coe (1953).Biology
This is a woodland species, possibly occurring in both coniferous and deciduous woodland. The larvae of the genus Melangyna are aphidophagous, but those of M. barbifrons are as yet unknown. The little evidence to date suggests that M. barbifrons is associated with shrub layers and canopy trees. Adults fly very early in the season and have been noted visiting sallows Salix sp. flowers.Distribution
Apparently disjunct: widely scattered across southern England to southern Cumbria and North Yorkshire, reappearing in the Highlands of Scotland. Records since 1990 include: Derbyshire, South-west Yorkshire, North-east Yorkshire and East Inverness & Nairn.Status
Lower Risk (Near Threatened) - Ball & Morris, 2010. Notable - Falk, 1991.
