Habitat preference: Chelifer cancroides was reported under dead wood bark in Lithuania (Krajčovičová et al. 2018). In Slovakia it has been found in bird nests, combined bird and mammal nests, and in synanthropic habitats (Christophoryová et al. 2017b). In Hungary it has been reported from henhouse (Kárpáthegyi 2007), from houses, under bark of oak tree, and in beehives (Novák 2011, 2012). During the present study this synanthropic species was found in beds, in books, in the attic of a church, in henhouses, and in and around houses.
Remarks: Chelifer cancroides was first recorded for Hungary by Tömösváry (1882a), and it is widespread across the country.
