The Wolf Spider female is a good caretaker of her young; something not usually expected with arachnids.
The Wolf Spider hunts at night, spending the daytime hiding in a burrow under stones, logs or other undisturbed places. They have been known to burrow in homes at times. Their large size makes them intimidating and feared. They are known to bite when handled, though their venom is not medically known to be very harmful to humans. Given their size, one can imagine the fangs are also proportionately large, adding to the pain of a bite.
After mating in the fall, males die and females overwinter. They lay their eggs in the spring and bundle them in a sac spun from spider silk. Once hatched, the small spiderlings climb on the back of the mother and spend the summer there, growing in size, but not to full maturity yet. Both mother and spiderlings overwinter together. The next summer, the spiderlings reach full size and maturity, leaving the mother and starting life on their own.

Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
