SeasonalityMale and female adults forage from May to September (Buddle 2000), but are more common from late May to mid June (Buddle et al 2000). IdentificationPardosa mackenziana belongs to the Pardosa nigra group which is represented in Canada and Alaska by four more species (Lowrie & Dondale 1981 in Dondale & Redner 1990). Most of wolf spiders are very similar and usually differences are based on male and female sexual characters, however, size, distribution and coloration patterns usually help to differentiate some species. Carapace (dorsal portion of the head region or cephalothorax) broad, dark brown with a dorso-medial longitudinal lighter band which is constricted in its anterior third, no marginal bands present. Mouthparts: Chelicerae and fangs the same color as carapace; labium, endites slightly lighter in color with a pale anterior border. Sternum (ventral plate between legs) light brown. Femora (3rd leg segment) and tibia (5th leg segment) dusky with three inconspicuous lighter rings; patella (4th leg segment), metatarsi (6th leg segment) and tarsi (7th leg segment) brown. Abdomen with no markings, dorsally dark, lighter ventrally. Males and Females similar in coloration pattern but males smaller. Male palps (see additional picture, articulated appendages anterior to 1st pair of legs): Medial apophysis (ma in palp image) with two projections, anterior projection longer, curved and with several minute “teeth” on its tip, posterior projection smaller, rounded (rather conical); terminal apophysis (ta in palp image) slender and curved, with internal border toothed. Female epigynum (see additional picture, located in the anterior ventral side of the abdomen): Longer than wide, with two lateral dark swellings (1 in image), median septum with anterior part long and narrow (2 in image) and posterior part broader and ridged (3 in image).
