Two pics of a spider found in a co-worker’s house in Tucson AZ in late September 2014. People come to me with their bug questions, but I’m not knowledgable about spiders. If someone can just get it to a rough group of spiders that’d be great. Just curious. Thanks so much.

We believe this is a female Western Spotted Orbweaver, Neoscona oaxacensis, a highly variable species. We matched your image to this image on BugGuide. Orbweavers are in the family Araneidae, and they are a harmless family of spiders. Orbweavers build large circular webs, the “classic” spider web. Most Orbweavers are sexually dimorphic, with the females being much larger than the males.
