Butterflies -Switzerland -EUROPA 2021.

The Woodland brown and the Scarce large blue – two butterflies that could hardly be more different. But they do have one thing in common: both are classified as endangered species in Switzerland.

The topic selected by PostEurop for this year’s EUROPA stamps is “Endangered national wildlife.” Switzerland’s contribution was produced by the highly dedicated scientific illustrator Nina Schwarz from Bern. The designs are of the wood- land brown (Lopinga achine) and the scarce large blue (Phengaris teleius) .The illustrations seek to highlight the delicate nature of these animals through a highly detailed and lifelike style.
