Lorković’s Brassy Ringlet is a satyrine butterfly endemic to the Alps from Slovenia through southern Austria to eastern Italy (De Groot et al 2009). The larvae feed on grasses (Rakosy & Jutzeler 2005). The preferred habitat is undisturbed alpine grassland with patches of bare ground, where the butterflies bask in the sun and feed on minerals (De Groot et al 2009). In Austria, piles of rubble overgrown with grasses are also an important habitat (Rakosy & Jutzeler 2005). Erebia calcaria was listed in Appendix II of the Bern Convention (Council of Europe 1979). Populations are threatened by habitat loss due to cattle grazing and construction of ski resorts (De Groot et al 2009, van Swaay et al 2012).
