Habitat
In my experience, this species lives in creosote bush flatlands in the Sonoran Desert (the submitted photos are at 1,500' in elevation). Webs are usually built no higher than 1 meter off the ground and contain a central silken tube adorned with the exoskeletons and remains of its prey. When threatened, the spider retreats inside. Small beetles seem to be a frequent prey, but could appear over represented due to their conspicuous remnants in the web. I have not seen this species' web, in my area, in anything other than a creosote bush. - Michael Hughes, 16 December, 2016
