Cheiracanthium inclusum

There was plenty of camphorweed, Heterotheca subaxillaris, flowering close to the Colorado River below the Loop 360 bridge when I visited on the morning of September 24. One flower head drew my attention because of the way some of its rays were pulled out of their normal positions. I’ve come to recognize that as the probable handiwork of a spider, and sure enough, there was one, which eventually moved around to a place where I could photograph it. Joe Lapp has helpfully identified it as Cheiracanthium inclusum, known as an American yellow sac spider. Out of focus in the background on the left is a fully developed camphorweed flower head, and on the right a bud beginning to open. The faint purple glow in a couple of places is once again from some purple bindweed flowers.
