Recorded Habitats: prairie grassland, stony or sandy beaches, quarries, dry creek beds, talus slopes, open tundra, herbs and shrubs at the margins of deciduous forests
Life & Natural History: Males collected mid-May to July. Females collected mid-May to October. Egg sacs collected June to early October. Likely produces more than one egg sac, and has a two-year life cycle in the northern part of its range, and a one-year life cylce in the southern part of its range (Pickavance, 2001).

Image(s) of Habitus:

Description: Carapace is dark reddish brown to black with a few radiating black lines, and may have pale median and submarginal bands. Sternum is dark brown to black, sometimes with a median yellow stripe at the anterior. Chelicerae are dark with pale longitudinal streaks, and two teeth on the retromargin of the fang furrow. Legs are orange with black streaks and indistict rings on the femora. Abdomen is almost black dorsally, with a large pale heart mark and a series of chevrons. Palp is unique because of its broad, flat terminal apophysis, and the slender, curved hook on its palea (Dondale & Redner, 1986).

Male Dimensions: A = 2.39 mm  A+B = 4.83 mm  C = 1.83 mm

Description: Colouration as in male, but pale bands on carapace are more distinct, and legs are lighter, with more distinct black rings. The epigynum is unique because of its deeply indented lateral margins, and its median septum, which is broadest at the level of the copulatory openings, and is tapered anteriorly (Dondale & Redner, 1986).

Female Dimensions: A = 2.55 mm  A+B = 5.69 mm  C = 1.98 mm
