The main habitat for Anoplius aethiops is in sandy or rocky areas where they have the ability to bury their prey (Evans I). Open areas such as fields and meadows are ideal but they have never been seen in open sand such as a beach. There is very little known about their natural nesting habitats, outside of how their young are nested, and it is predicted that Anoplius aethiops could live primarily in tall grasses and simply use the gravel like habitat for burying their prey and allowing reproduction. A. aethiops are solitary creatures except for their mating time and are generally found in the northern United States and Southern Canada. They are less common in the southeastern part of the states most likely due to competition with another, very similar species, A. atramentarius (pictured below) (Evans II).
