Species Account

Sutton & Beaumont, 1989: This species has been recorded from all five vice-counties with confirmed records from vice-counties 61 to 64 and it is likely that it will turn out to be quite common and widespread (see O. strigilis (Linnaeus) above). It will probably be found that the Minors currently recorded as strigilis will actually be a mixture in most areas, with the balance of composition varying depending on the local habitat. However, the current species does seem most widespread on the evidence given so far. (60% of the three 'difficult' minors recorded at Huntington (VC62) proved to be this species (AHF pers. comm.)).

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.
