Zygiella carpenteri
Zygiella carpenteri is an orb-weaving spider native to western North America. It was formerly classified in the genus Zygiella but has been reclassified to Parazygiella carpenteri in some taxonomic treatments. The species constructs complete orb webs rather than the incomplete webs with missing sectors typical of some related species. It occurs in disjunct populations in the Sierra Nevada mountains, the California coast, and southeastern Washington.
