Host plants:
The caterpillar is likely to feed on grasses (especially Poaceae) like those of the related species.
Habitat:
Maniola nurag inhabits nutrient-poor grassland-like terrain, such as quarries, grassy and shrub-rich slopes, loose scrub, embankments, rocky terrain, etc. from 400m to 1300m above sea level.
Life cycle:
The caterpillar overwinters. The adults fly from May to July or August. I met a first male in the central mountains of Sardinia on 24 May 2012 at 800m above sea level.
Remarks:
Maniola nurag is endemic to the higher elevations of Sardinia and there quite widespread. The closely related Maniola jurtina flies in Sardinia only at lower altitudes. Of this species, I met many adults for example in the coastal dunes of the Sinis Peninsula in May 2012.
