Range
British Columbia to Newfoundland, south to Utah, Oklahoma, and North Carolina.(2) However, it is noted by Levi (1974b) that this species may be introduced because of its close association with buildings and because its range is very similar to the introduced Araneus diadematus (which is also a holarctic species now)... so this range may expand over time (see note below).

**We've received recent voucher specimens from Long Beach, California (thanks to Dr. Vincent) that may indicate the distribution of this species has greatly expanded since the range listed in Dondale et al. 2003 (see CA voucher male & female).
