Chroniony gatunek pająka z rodziny skakunowatych Salticidae, strojniś nadobny Philaeus chrysops (Poda, 1761), został odnotowany na Dolnym Śląsku, na terenie dawnych oraz wciąż użytkowanych poligonów w okolicach Świętoszowa, Ławszowej, Golnic i Kozłowa. Znaczna część tych obszarów znajduje się w obrębie sieci Natura 2000 (Wrzosowiska Świętoszowsko-Ławszowskie, Wrzosowisko Przemkowskie). W artykule dyskutowane są kwestie dotyczące rozmieszczenia tego gatunku w Polsce i Europie, jego wybiórczości środowiskowej oraz zasadności i możliwości ochrony.

A protected spider species, Beautiful Jumper Philaeus chrysops (Poda, 1761) from the family of jumping spiders (Salticidae) was recorded on a few localities in Lower Silesia (Poland). It was found during the inventory of the military training areas - both the former ones and those still used by the army - located near Golnice, Kozłów, Ławszowa and Świętoszów. Lately, the major part of this region has been included in the Natura 2000 Network, as "Wrzosowiska Świętoszowsko-Ławszowskie" and "Wrzosowisko Przemkowskie". Ph. chrysops was found in its typical habitats, i.e. inland dunes with pioneer grasslands and heathlands that had been preserved from natural succession due to military activity and uncontrolled fires. These habitats are regarded as valuable, because they significantly contribute to the overall diversity of the region. However, the ecological succession could be observed in a large part of this area. The majority of Ph. chrysops specimens inhabited low shrubs of wild black cherry (Primus serotina), Scots pine (Pinns sylvestris) and heather (Calluna vulgaris). We claim that the two previous observations (from as early as the 19th and the beginning of the 20th century) from southwest Poland are uncertain, so the first confirmed localities of this species in the region are presented in this paper. The species is known only from a few, scattered localities in Poland, however, it also occurs in western Germany near the border with Poland. The species is common in southern Europe. Nonetheless, its peripheral populations in northern Europe seem to be important, because Beautiful Jumper occurs there in rare and endangered habitats.
