This is an opportunistic burrowing species of wolf spider that grows to about 1'' (leg-span). I have 3 of these, as there is a massive colony in my neighbors yard (there are so many that my neighbor made a communal set-up of 8 individuals!). As adults they are dark colored with even darker stripes. The sub-adults and younger are more lightly colored and sometimes lack any form of stripes. The males are small growing to about 1/2'' to 5/8''. The males also look different. They are lighter colored with darker forelegs and have very large pedipalps (given they are male). I have two sub-adult females, one younger than the other, and one mature male, who quite honestly might not live to 2019 Finally, here are a few pics (sry if they r bad):
