Investigations on basic population characters of the lycosid spider Arctosa cinerea were conducted from June 1994 to July 1995. The spiders were individually marked and recaptured to estimate abundance and home range size. Maximum spider densities found were 0.3 ind./m2 . During their larval stages and during the first four weeks as adults, the spiders prefer gravelbanks where they hide under stones during the day. As they get older they prefer sandy substrates for the establishment of their burrows. A. cinerea has a two year life cycle. The species is diplochronous with reproductive periods in autumn and spring. The adult sex ratio is biased towards females (1 : 1,8). Maximum home ranges were 1 .260 m 2 for males and 1 .140 m 2 for females.
