Abstract
The ivy bee Colletes hederae was recorded in the west and south of Poland in September 2023. While C. hederae is expanding its range in Europe, these are most probably the first records of the species in this country. The two localities, Górzyca (at the Polish-German border) and Kraków (S Poland), are situated about 450 km apart from each other. This suggests that the species is colonising the territory of Poland simultaneously from Germany, as well as from the Czech Republic and/or Slovakia.
