Taking the regular overwintering of spider species in land snail shells as a model, we studied environmental conditions affecting the choice of overwintering sites in three jumping spider species: Pellenes tripunctatus, Pellenes nigrociliatus, and Attulus penicillatus. The research was conducted at 11 steppe localities on calcareous bedrock with abundant empty shells (mainly Caucasotachea vindobonensis and Xerolenta obvia). We documented 889 shells and collected 186 of them, of which 113 were inhabited by 146 spider individuals (13 species). Our three focal species made up 81.5% of these. We found different environmental preferences between the sexes in Pellenes tripunctatus and Pellenes nigrociliatus. These females preferred shells with more vegetation nearby. In the case of Pellenes tripunctatus, these were shells with a higher proportion of herbs, whereas Pellenes nigrociliatus selected for a higher proportion of moss. In the immediate vicinity of the shells, environmental conditions did not differ significantly. We found insufficient Attulus penicillatus to determine any preferences. We also recorded six overwintering Pellenes tripunctatus individuals in a single shell (in environmental conditions preferred by females), consisting of five females and one male, which indicated an unusual social behavior for these spider species.

Overwintering of spiders in empty snail shells is a little studied topic and in Slovakia similar research has not been carried out yet. Collecting shells was carried out in the eastern part of Slovakia, in winter at the turn of 2012/2013 and 2013/2014. The study was conducted both at the steppe like and post-industrial habitats. A total of 1085 shells were collected with a spider occupation rate 10.69 %. All acquired 116 spiders were classified in ten families. The most abundant spider family was the Salticidae, with a dominant species Pellenes tripunctatus (Walckenaer, 1802). Significant records include Cheiracanthium montanum (L. Koch, 1877) which is considered as vulnerable and Sitticus penicillatus (Simon, 1875) with a lower risk threat according to Red List of Slovakian spiders.
