Euchloe tagis

Euchloe tagis, the Portuguese dappled white, is a butterfly in the family Pieridae.

It ranges through southern Europe where it is found from Portugal to northwestern Italy and northern Africa (there are local populations in Morocco and Algeria).

This species is found in local, discrete populations limited to fairly small areas of suitable habitat which is invariably made of calcareous outcrops with Mediterranean scrubland where the food plants, crucifers of the genus Iberis are found.
