Distribution

This species has a markedly northern distribution. It is frequent from North Wales and the Pennines northwards, and is amongst the commonest Cheilosia in Scotland. There are a few records from southern England, but confusion with C. antiqua and C. nigripes is possible and consequently several such records have been discounted.
