This taxon is widespread in warm montane and subalpine grasslands, with only some individuals recorded at high elevations (> 2600 m ). According to the available data, the specimen observed at 2840 m (Passo Vallanta, Pontechianale; 27/08/2020 ; DG ) represents a new altitudinal record for S. scalaris in Italy and in the whole W-Alpine region.
