Cheilosia species B sensu Stubbs & Falk, 1983Nomenclature
The identity of "Cheilosia species B" is uncertain, but is thought to be either C. gigantea Zetterstedt, 1838 or the recently separated and little known C. ingerae Nielsen & Claussen, 2001. This cannot be resolved unless more specimens are found.Biology
The larval food plants of the most likely contender for Cheilosia species B, C. gigantea, are Northern Dock Rumex longifolius and Scottish Dock Rumex aquaticus, both of which have highly restricted distributions in Scotland and northern England.Distribution
There is only one record of a single male found by Iain MacGowan on the banks of the River Dee near Ballater in the central Highlands of Scotland on 30/05/1981.Status
