Pardosa pullata is one of the commonest species in the genus, being found all over the UK and Northern Europe. It is a hunting spider (also known as "wolf" spider) and can often be seen running around on sunny days on the ground in fields and on paths. The photograph is of a preserved female of the species. There are two epigynes shown in the gallery. Whilst I believe they are both from specimens of Pardosa pullata there are some interesting differences.
