The Azerbaijani Post has issued a stamp featuring a Mountain Apollo (Parnassius Apollo) butterfly.
This species is of interest to entomologists due to the variety of subspecies.
The Apollo Butterfly is a very beautiful species of butterfly that were once widespread all over the European and Asian meadows. Unfortunately, nowadays they're almost extinct and very rarely seen. They inhabit territories in meadows and mountains up to 2200 metres above sea level, ranging from Europe to Central Russia.
