This cold Pennsylvania morning, this spider was on the rug just inside the door to the patio.
In searching for a matching photo, I noticed something: Many similar spiders have 4 pairs of legs plus a pair of “half-length” legs up-front. This spider lacks those “half-legs”.
This spider has them but they are tucked under so they look like knobs at either side of the head. They are also called pedipalps and are used to manipulate food. In mature males, the genitalia are at the ends of the pedipalps.
This looks to be a Wolf Spider, possibly one of the Tigrosa species in the family Lycosidae.
