A nonnative population of all-female spotted whiptails from the Asidoscelis flagellicauda/sonorae complex was reported from suburban Irvine, Orange County in 2015 and 2016. We report additional suburban observations dating back to 2010 from Laguna Woods and extending the range south ~6 km southwest to Aliso Viejo. We hope that this and other exotic reptile species will remain restricted to highly altered urban environments and not threaten native species in natural habitats.
