Notes: Chernes hahnii is a typical dendrophilous species that lives in Bratislava mainly under the bark of trees ( ChristophoryovÁ 2010; KrajčovičovÁ & ChristophoryovÁ 2014; ChristophoryovÁ et al. 2017b; ČervenÁ et al. 2020b; Garbiec et al. 2022) and in tree hollows ( KrajčovičovÁ & ChristophoryovÁ 2014; ChristophoryovÁ et al. 2017b). It also lives in bird nests and anthills ( Christophoryová 2010; Christophoryová et al. 2011a, 2017a; KrajčovičovÁ et al. 2015). It is rarely found in soil and dead wood ( Krumpál & Christophoryová 2007; Christophoryová et al. 2016; ČervenÁ et al. 2020b), Malaise traps ( KrumpÁl & ChristophoryovÁ 2007) and compost ( KaňuchovÁ et al. 2015). The distribution of the species in Bratislava was extended by more than 40 new sampling sites, and samples were mainly taken from birds’ nests and under the bark of trees.
