Common in grassland, woodland rides, gardens and a wide range of other habitats throughout much of the British Isles. In Hampshire and on the Isle of Wight widespread and common, possibly more so than Marbled Minor O. strigilis
. Wingspan 24-27 mm. Marbled Minor O. strigilis
, Rufous Minor O. versicolor
and Tawny Marbled Minor O. latruncula
, especially their melanic forms, can only reliably be separated by dissection of the genitalia. Typical examples of Tawny Marbled Minor have the forewing blackish brown, the outer area with a distinct coppery burnish; reniform and orbicular stigmata usually indistinct except with a lens; antemedian line dentate, often very indistinct and incomplete; postmedian line curving more evenly to dorsum than in Marbled Minor (MBGBI Vol 10). It is possible with experience to assign well-marked individuals to Tawny Marbled Minor at a particular site once the observer is familiar with the forms present in that area. Larva feeds on various grasses, including Cock's-foot.
