This Wolfspider is living in places near water and is a common guest on garden ponds, like the specimen on this picture, which is sucking out a fly. Just like Pirata pirata it can walk on water and may grab insects that have fallen on the surface. Wolfspiders make no web, but are aggressive hunters that catch their prey by jumping.
This predatory behaviour is found in the name Pardosa, from the Greek Pardos meaning panther. (Think of: leopard from leopardus, "lion-panther"). The addition amentata might have something to do with the ring shaped spots on the legs. The cf. short indicates that the species can not be made out for certain with only this picture.
Funny thing: the spider seems to be looking our way, but in fact those are just two from the four eyes.
