Polyommatus admetus inhabits steppe slopes, extensive grazing land and other nutrient-poor grasslands.
The young caterpillar overwinters. I met adults in Northern Greece in the area of
the Prespa Lakes quite common in mid-July.
Polyommatus admetus is in decline due to cultivation, overgrazing and overbuilding of its habitats.
Polyommatus admetus is found in the Balkans from Hungary and Croatia to Greece.
