Unlike Phidippus californicus, which lives in the same habitat, it builds a large and prominent nest among the branches of a bush to house its egg cocoon.[1]

Adult males, unmated adult and subadult females can be found in late August.

P. octopunctatus has been observed to hunt large prey, such as grasshoppers and bees.[1]
