thank you for your kind words.
Parnassius apollo still exists widespread in the Austrian Alps, above limestone as well as above silicate grounds - but always in rather small numbers, and in rather remote, steep, rocky areas. Just yesterday on a sunday walk, I totally unexpectingly noticed a group of four or five individuals in the slopes of Schneeberg 70km south of Vienna, two of them even gave me the chance to take a few pictures of them.
Didn't know that specimens from Austria were introduced to Poland, makes me happy to hear that from you. I am sure they will enjoy their new home. Looking forward to seeing them pictured someday here on TN.
With thanks, and best regards,
Parnassius apollo. (46)
