SeasonalityMales collected May to July, females and egg sacs from June to October (Dondale & Redner, 1990).
IdentificationPardosa uintana looks similar to other Pardosa species, with a carapace that is dark brown to black, but which has a lighter band down the middle, and a dark, mottled abdomen. The legs are also dark brown, but become paler towards the tips and have indistinct, black rings (Lowrie & Dondale, 1981). The sternum is dark and the chelicerae light brown. Females and males have similar colouration, but females (length = 6.27 +/- 0.73 mm) are longer than males (length = 5.69 +/- 0.40 mm). Females also have a larger carapace width (2.24+/-0.09 mm) than males (2.18+/-0.13 mm)(Dondale & Redner, 1990). Pardosa uintana can be distinguished from other Pardosa by the shape of the epigynum in females and the palp in males. The epigynum is unique because of its lateral swellings that converge posteriorly, and because of its ovoid spermathecae, which are more than twice as long as they are wide, and which can best be seen after dissection. The palp is unique because of its tegulum, which can be seen from a side view to protrude greatly at the base (Lowrie & Dondale, 1981), and also because of its stout embolus, which has a helical tip, and its median apophysis with a short, slender, curved distal process (Dondale & Redner, 1990).

Life History
Egg sacs have 41-57 eggs, and more than one sac may be produced (Lowrie & Dondale, 1981).
Conservation
Not at risk (COSEWIC, June 2005).

Like other wolf spiders, Pardosa uintana hunts actively, by pouncing on prey and holding it with its front legs, while mashing it up with its chelicerae (Gertsch, 1979) and is a general predator on arthropods, including insects and other spiders.
Range
Pardosa uintana occurs across Canada and the northern United Sates, from Alaska in the northwest, to Newfoundland in the east, south to Utah, Colorado, and New England (Dondale & Redner, 1990).
