Western Parson Spider (Herpyllus propinquus)
The western parson spider's (Herpyllus propinquus) common name is attributed to its distinctly scalloped median abdominal stripe, which is said to resemble an old-fashioned cravat worn by parsons or ministers. This species
is a cursorial hunter; instead of using a web to catch its prey, it is specially adapted for high-speed endurance running. Although its venom is not considered to be medically significant like that of the western black widow (Latrodectus hesperus), there have been reports of bites resulting in excessive swelling and soreness.
