Black and White orb spider from southern Utah
This orb spider was found in a canyon in Southern Utah. Do you know what kind of orb it is and what areas is it common to be found? Thank you,

neoscona white utah White Orb Weaver from Utah: Banded Garden Spider

Wow Matthew,
We have never seen such a white Orb Weaver. We believe this is the highly variable Neoscona Oaxacensis, the Western Spotted Orb Weaver. It is a common species in Utah, but the white coloration is not something we have been able to locate in about 30 minutes of web searching. We will see if Eric Eaton has an opinion on this beauty.

Also, the “white orb weaver from Utah” is an exceptionally pale specimen of the banded garden spider, Argiope trifasciata. Specimens of arthropods from arid lands are often much more lightly colored than their counterparts in cooler, wetter places.
Eric
