SeasonalityMales collected mid-May to July, females mid-May to October, and egg sacs June to early October.
IdentificationPardosa tesquorum looks similar to other Pardosa, with a dark reddish brown to black carapace that has a few radiating black lines, and pale median and submarginal bands, which are often indistinct or absent, especially anteriorly and in the male, and are thus not particularly useful characters to rely upon for identification. The sternum is dark brown to black, but sometimes has a yellow stripe down the middle at the anterior. The chelicerae are dark with pale, longitudinal streaks, and with two teeth on the retromargin of the fang furrow. (These will not be seen without a microscope.) The legs are orange with black streaks, and indistinct rings on the femora. The female has lighter legs and more distinct black rings than the male. The abdomen is almost black dorsally, but with a large pale heart mark, and a series of pale chevrons. The underside is yellow or gray, and darker toward the middle (Dondale & Redner, 1986). The female (length = 5.69 +/- 0.63 mm) is slightly longer than the male (length = 4.83 +/- 0.44 mm), with a slightly wider carapace (1.98 +/- 0.13 mm) than the male (1.83 +/- 0.15 mm). In order to distinguish P. tesquorum from other Pardosa, it is necessary to look at palpal and epigynal characteristics. The male palp is unique because of its terminal apophysis, which is broad and flat, and because of the slender curved hook on its palea. The epigynum is unique because of its median septum. This is broadest level with the copulatory openings, tapered anteriorly, and has deeply indented lateral margins of the epigynal plate (Dondale & Redner, 1986).
