They are around 4.7–7.1 mm long in length and are primarily found in the arid southwestern parts of the United States.

Semi-social, in the case of P. oweni, refers to the coexistence of facultatively communal and solitary females within the same habitat.

This lack of true cooperation means these spiders do not share prey items, do not work together when spinning webs and do not care for one another's young.

[5] The coexistence of both solitary and communal species within the same habitat can be explained by both tactics have similar net reproductive success values.

The number of surviving offspring of communal and solitary beings does not vary significantly, which mostly due to the parasitism by pteromalid wasps (Arachnopteromalus dasys).

[7] There is a significant difference in the amount of time a female spider spends during feeding solely based on if she is communal or solitary.

[7] Experimentally, reducing communal groups' numbers led to an increase in individual feeding rates.

The benefit is their ability to dominate and occupy areas that have a significantly high abundance of insects, which outweighs the cost of competition between each other.

When the number of web building attachment sites are scarce the population of P. oweni in the area tends to be more communal.

These orbs share support lines between them, and within these communal webs there is at least one retreat area that is used by all members within the groups.

[6] When a female spider creates an egg case, it is given a distinctive color marking that corresponds with the mother.

The mother then moves into a safe "retreat area" and stays here with her egg-case stuck to her spinnerets and held by her fourth pair of legs.

Once the young spiders have hatched from the egg case, the female discards it and leaves the retreat area to spin a new prey-capture orb.

In general, most related and unrelated females tolerate the presence of spiderlings if they are living within a communal setting.

These groups tend to form in places where ideal web building sites are scarce and potential prey insects abound.

Communal groups allow for multiple females to protect their site while still benefiting from the easy access prey.

[5] This communal behavior is not considered cooperation since these females do not collaborate in hunting, do not work together on spinning webs, and do not care for each other's young.

This predation was done by both male and female A. baboquivari and involved the consumption of both adults and immature eggs of P. oweni.
