In 1999–2019, spiders and millipedes in Žleby, a municipality in the District of Kutná Hora were recorded. At 22 sites, the author collected or photographed 854 spider and 642 millipede specimens belonging to 121 spider and 29 millipede species. Most of them are common, however, spiders Ero aphana, Nematogmus sanguinolentus, Silometopus elegans and Amaurobius jugorum, and millipedes Cylindroiulus arborum and Haploporatia eremita, are ecologically significant. The most (millipede) species rich site at Žleby were the left bank of the Doubrava River and the lime alley. During the long-termed survey on spiders, the first occurrence of five recently spreading species (Pholcus phalangioides, Ebrechtella tricuspidata, Argiope bruennichi, Steatoda triangulosa and Ero aphana) was documented at Žleby.

A total of 151 spider species from 27 families and 4 harvestman species from 2 families were found during the zoological research of several sites in Podyjí National Park during 2018. Seventeen of the species found are listed in the Red List of Spiders of the Czech Republic. The most interesting species are Alopecosa sulzeri (Pavesi, 1873), Amaurobius jugorum L. Koch, 1868, Araniella inconspicua (Simon, 1874), Callilepis schuszteri (Herman, 1879), Clubiona marmorata L. Koch, 1866, Echemus angustifrons (Westring, 1861), Gnaphosa lugubris (C. L. Koch, 1839), Gnaphosa opaca Herman, 1879, Gongylidiellum murcidum Simon, 1884, Haplodrassus minor (O. P.-Cambridge, 1879), Kishidaia conspicua (L. Koch, 1866), Micaria formicaria (Sundevall, 1831), Pseudeuophrys obsoleta (Simon, 1868), Saaristoa abnormis (Blackwall, 1841), Tmarus piger
(Walckenaer, 1802), Xysticus luctator L. Koch, 1870, Zelotes erebeus (Thorell, 1871) and the harvestmen Egaenus convexus (C. L. Koch, 1835).

While the majority of the Central European landscape would be covered by forests without human influence, rocky areas form isolated, islet-like, natural, non-forest habitats. The surface of some of these non-forested areas is composed of bare bedrock or products of its erosional breakdown (without a soil layer) such as gravel, sand banks, sand dunes, scree slopes and rock outcrop habitats. These habitats harbour specialized  spider species that depend on their specific substratum and microclimate (Růžička 2000). Out of these habitats, rock walls (and scree slopes) form one of the most distinct ecological gradients of any terrestrial ecosystem (Larson et al. 1989, Růžička et al. 1995). They provide habitats with extremely warm and cold microclimatic conditions in close proximity. They also belong to habitats almost unknown until now due to the technical and practical problems of sampling.

Sandstones can form extensive systems of rocks, sometimes with a broad spectrum of meso- and microhabitats due to their very dynamic relief. Sandstone rocks are characterised by a marked contrast between forested plateau and bare vertical rock walls (Balatka and Sládek 1984). Upper margins of rocks are dry, vertical rock walls can be sun-exposed, dry and bare, or shady and humid and hence covered by mosses. Spaces with an extremely cold climate can occur in deep gorges. The aim of this study is to evaluate available data on the species composition of spider assemblages in sandstone rocks, including new data about spiders on rock walls in the Bohemian Switzerland (České Švýcarsko) National Park.
