Eastern Parson Spider

The Eastern Parson Spider (Herpyllus ecclesiasticus), is a member of the ground spider family Gnaphosidae. It is found throughout the eastern half of North America, as its name suggests. The majority of specimens are between 10 and 20 millimeters long, with males being smaller than females in length. They have fine hairs all over them and primarily have a black or dark grey appearance. A white stripe on their abdomens mimics a cravat, a style of necktie worn by clergymen known as parsons in the 18th century.

Eastern parson spiders don't hunt for victims in webs. They can run exceedingly swiftly in pursuit of insects and love to ambush their victim. Although their bite is not lethal, it is known to be quite painful. Since they often prey on household pests, most people consider them beneficial and tend to leave them alone.
