Ecology.

Above the 55 th parallel northwards it is an exclusively synanthropic species (Kovblyuk and Kastrygina 2015; Nentwig et al. 2024), but southwards it can be found in natural biotopes – under stones and in rock crevices (Tyshchenko 1971). In Crimea, M. nebulosus is rare, recorded in Sevastopol and Feodosia (Kovblyuk and Kastrygina 2015), and only once in the subterranean biotopes (present data). Also, this species was recorded as a troglophile in the Kristalnaya Cave in Ternopol region, Ukraine (Evtushenko 2004; Zagorodniuk and Vargovitsh 2004). In the Crimean caves, the ecological confinement of M. nebulosus is not entirely clear, it is probably a subtroglophile.
