Abstract
In May 2006, Salticidae jumping spiders were investigated in the Cedynski Landscape Park in two xerothermic biotopes, a railway embankment and an old pine clearing. Ten species of jumping spiders and two morphospecies were recorded, the most abundant being Aelurillus v-insignitus, Asianellus festivus, and Evarcha arcuata. Species richness was measured and two different collecting methods were tested.
