Ecology.

A troglophile and synanthropic species (Nentwig et al. 2024). In Crimea, it has been recorded everywhere as a synanthropic, except for the southern coast where it occurs in natural habitats (Kovblyuk and Kastrygina 2015). In the Crimean caves, the ecological association of S. triangulosa remains unclear. Since we have collected only two specimens from the entrances of Tshernoretshenskaya and Izumrudnaya caves, it is likely to be a subtroglophile.
