Recorded Habitats:
This species is typically found near water bodies and has been considered semi-aquatic, having a strong positive correlation with moist littoral areas (Graham et al., 2003) such as salt marshes (Dondale & Redner, 1990), meadows (Dondale & Redner, 1990; Nordstrom & Buckle, 2002), bogs, swamps, beaches (Aitchison-Benell & Dondale, 1990) and peatlands (Dondale & Redner, 1994). However, it has also been collected in alpine tundra, conifer forests, or forage crops.
Life & Natural History:
Like many other Pardosa species, P. fuscula has a biennial life cycle (Pickavance, 2001). Copulation events may occur throughout the summer because females with egg sacs have been collected from late May to mid October (Dondale & Redner, 1990). Copulation is more frequent during August because spiderlings are more abundant in September than in other months (Pickavance, 2001). Like other Pardosa species, P. fuscula immatures overwinter twice before reaching adulthood (Pickavance, 2001).

Details About Males
Description:
Carapace broad, dark brown, darker in the eye region, with two longitudinal lighter bands near the lateral edges, one smaller stripe the same color, over the dorsal mid line covering just the thoracic groove. Mouthparts: Chelicerae, labium, and endites dark brown. Sternum dark brown. Coxae and legs dark and dusky with dorsal black streaks, especially on femora. Abdomen dark brown to black with an antero-dorsal light patch, lighter ventrally.

Details About Females
Description:
Similar to males but the two longitudinal light bands near the lateral edge are more distinct. The overall coloration is lighter than in males. Epigynum: Wider than long to sub-quadrate, lateral plates broadly rounded on each side, posterior endings swollen, anterior part of septum slender and narrow, posterior part triangular fitting between posterior ends of lateral plates, atrium broad and rounded.
Female Dimensions:
A+B = 7.22 mm
A = 3.33 mm
C = 2.64 mm
