It is distributed in Europe, Turkey, Caucasus, Russia to Central Asia and China ( World Spider Catalog 2020 ). It can be found in mainland Italy ( Pantini and Isaia 2019 ). Notes It is a widespread species in many open habitats, such as disturbed grasslands, agricultural fields and river pebbles. It is found mainly in low vegetation and in litter. It is a mainly nocturnal active species, which has a low resistance to drying and low temperatures. It is a weaver spider of simple webs on the ground ( Isaia et al. 2007 ). Adults of both sexes have been recorded throughout the year, most often between late spring and mid-summer. Individuals can either overwinter as immature individual or as eggs, depending on the time of reproduction ( Harvey et al. 2002 ).
