I live in the Boulder area and hike the Greenbelt Plateau and Flatirons Vista open space.
Wolf spiders were everywhere along the trail. I never knew that wolf spiders could get that big. One was four inches across. He was an aggressive little guy. He chased my walking stick when I put it in front of him.
I didn’t see any webs. They hide in holes and ambush. Pretty certain that they were wolf spiders.
I have lived in Colorado all of my life and didn’t know this.
The ‘’he’’ is a ‘’she’’. Male spiders serve one purpose— mating. After that it’s Good Night Irene. The female eats him.
