- The flat, disc-shaped egg case is deposited in a silken retreat where the female guards it, usually under tree bark. One recorded egg sac in Connecticut was 17 millimeters in diameter and held 130 spiderlings (Kaston 1948).
- West of the Continental Divide, there is a nearly identical species named Herpyllus propinquus (the “Western Parson Spider”). The two species can’t be separated from one another using only outward appearances, they look too much alike, so the details of the genitalia must be examined under a microscope.
- Spider is very fast and difficult to catch, let alone photograph.
- Though members of the entire family Gnaphosidae are collectively nicknamed “ground spiders,” that is not always where they’re found, especially fairly synanthropic species like this one.
