The underside is characterized by black and yellow scales, which create a greenish-white pattern.

Euchloe ausonia occurs in Europe in central and southern Italy as well as in the Balkan Peninsula including most of the larger, Greek islands.

In the east, the presence in the south continues to Israel and Jordan and in the east to northern Iraq, Iran and Afghanistan, to the north via the Caucasus up to southern Kazakhstan and across the Palearctic to Tian Shan, Altai and Tibet.

The species prefers rocky slopes, rocky meadows, abandoned or neglected cultivated land, open olive groves, roadsides, mountain meadows and also forest edges up to 2000 m above sea level.

The larvae feed on the flowers and young fruits of Sinapis arvensis, Isatis tinctoria, Isatis glauca, Aethionema saxatile, Iberis sempervirens, Biscutella mollis, Biscutella laevigata, Bunias erucago and Aurinia saxatilis.

[2] Because of these taxonomic problems older literature often refers to a very different geographical distribution and also the number of subspecies is not certain.
