Natural History, Phenology & Image(s)
Feeding Guild:† ground runners
†Feeding guild when noted defined by Uetz, G. W., J. Halaj, and A. B. Cady. 1999. Guild structure of spiders in major crops. Journal of Arachnology 27:270-280. PDF
Recorded Habitats: short grass, among herbs along streams, dry stony river beds and lakeshores, cultivated fields, along roadsides, open deciduous forest, sphagnum bogs
Life & Natural History: Males collected April to July. Females collected April to October. Egg sacs found late May to October. This spider decreases in relative abundance with increasing forest stand age (Buddle et al., 2000). No relationship was found between Pardosa xerampelina abundance and soil moisture in a study of habitat affinities of spiders living near a freshwater pond (Graham et al., 2003).

Details About Males
Description: Carapace is dark brown to black, with several radiating black lines, and may have a pale median area, which is widest around the dorsal groove (Dondale & Redner, 1986). Sternum is nearly black, but may have a pale median line (Chamberlin, 1908). Femora are dark brown and may have broad, indistinct black rings, but the ends of the legs are a lighter brownish orange. Chelicerae are dark brown, but paler towards the middle. Abdomen is dark reddish brown to black and may have a dull red heart mark (Dondale & Redner, 1986) or a series of brown chevrons (Chamberlin, 1908). The embolus of the palp is long and stout at the base, but slender and slightly curved distally. The distinguishing palpal character is an elongate median apophysis which, from a ventral view, conceals most of the embolus (Dondale & Redner, 1986).

Details About Females
Description: Colouration as in male, but pale median area on carapace is more prominent, and females have pale submarginal bands, as well as darker rings on the femora. The distinguishing epigynal characters are shallow hood cavities that are not directed mesally, and a median septum that widens anteriorly (Dondale & Redner, 1986).
