Pawica gruszówka Saturnia pyri (Denis & Schiffermüller, 1775) (Lepidoptera: Saturniidae) na Śląsku Opolskim i komentarz do jej występowania w Polsce

The Great Peacock Saturnia pyri (Denis & Schiffermüller, 1775) (Lepidoptera: Saturniidae) in Opole Silesia, with notes on its occurrence in Poland.The Great Peacock (Saturnia pyri) is one of the least frequently recorded moths in the Polish fauna. Until now, only historical sightings from Zamość (Lublin Region) and a less certain, old record from Racibórz (Silesia) were known. In 2023, for the first time since the 1930s, the species was observed in Poland in Głubczyce (Opole Silesia, SW Poland). A single male specimen was found resting diurnally on the wall of a building. This record is discussed in the context of the current range expansion of S. pyri in Silesian and Central Moravian territories of the Czech Republic and should be treated as a result of this natural process. Scarce evidence and published notes regarding the past occurrence of the species in Poland are also reviewed.
