Unknown Spotting ( Spider Webs And Prey )

I went into the garage, looking for some insects to photograph. After about twenty minutes, I found some spider webs, with some non-alive prey on them, and in the surrounding area. I found these spider webs and prey, in a corner, on a wall, on the right side of the garage. First photo, shows a non-alive arthropod, that has been eaten by a spider. Second photo, shows a larger area of the spider webs, and some non-alive prey. Third photo, shows the same arthropod, that had been eaten by a spider. Fourth photo, shows a larger area of the spider webs, and some non-alive prey. I did not see any spider on the webs, or in the surrounding area. I only saw some spider webs, and some non-alive prey.
