Cheilosia albitarsis

Cheilosia albitarsis (Meigen, 1822)


This species and C. ranunculi were separated by Doczkal (2000). Any records prior to this date can only be accepted if supported by a voucher specimen.

Biology & ecology:

The larvae of C. albitarsis (agg.) have been found in the rootstocks of large Ranunculus repens plants in late summer. Adults can be found in damp meadows, marshy places and grassy woodland rides, where they are most frequently seen at flowers of buttercups Ranunculus repens and R. bulbosus (rarely R. acris), but other white and yellow flowers are also visited. According to Speight (2010) this is an 'anthropogenic species, favoured by present-day farming practices.'


This is a widely distributed species that can be expected to occur in the majority of lowland damp habitats that support Ranunculus repens. The distribution map reflects the limitations of data submitted prior to 2000. Current evidence suggest that C. albitarsis is more widely distributed and abundant in the north and extends further into Scotland than C. ranunculi of which few specimens have been found amongst Scottish material pewviously identified as "C. albitarsis" (Rotheray & Wilkinson, 2010).

Status & conservation:

The plot of proportion of records received is for C. albitarsis and C. ranunculi combined and shows no obvious change.

Recorded from 1282 hectads since 1990.
