New data on the distribution of Parnopes grandior (Pallas, 1771) (Hymenoptera: Chrysididae) in northern Poland: habitat conditions propitious to this rare cuckoo-wasp species

Abstract

Abstract Parnopes grandior is a species that until recently was on the brink of extinction in Poland. Current data, however, indicates that it is expanding north-westwards. Most records of this species come from after the year 2000, primarily in northern Poland, especially in the north-eastern part of the country. Simultaneously, our research has shown that anthropogenic habitats like sand quarries and military training grounds are optimal sites for P. grandior.
