Yorkshire Status: Rare and local resident.

Sutton & Beaumont, 1989: This species is recorded as widespread and often common. However, melanics prevail in O. strigilis, O. versicolor (Borkhausen) and O. latruncula (Denis & Schifferrnuller) and they cannot be separated on wing markings alone. In Sheffield, when genitalia checks were made most specimens, originally put as this species, were found to be O. latruncula (Garland, 1979). However, in Derbyshire O. versicolor has been found to be as common as, or more common than, O. strigilis in some areas (Harrison & Sterling, 1986). Thus the status of this species in the County needs more careful examination before sweeping statements can be made, although there are already comments on relative abundances from several areas in the County. There are definite records from all five vice-counties.

2012 (CHF): This species is of course much more common than the distribution map suggests. It is not considered safe to separate Marbled Minor and Tawny Marbled Minor on the basis of forewing markings and they should be recorded as the aggregate species unless they have been dissected. There are confirmed records of this species from all over the county and it is likely to be widespread and common.
