[email protected] www.pinyon-env.com Errata for the Report: Butterfly Monitoring and Inventories Spring Mountains National Recreation Area Clark County, NV October 15, 2011 Andrea Sever 2005-PINYON-570C, Butterfly Monitoring in the Spring Mountains SNPLMA PROJECT # CC-32 On page 7 the author incorrectly cited Boyd (2004) among the reports postulating that Chrysothamnus nauseosus may be a larval host plant for Chlosyne acastus robusta. In his 2004 report, Boyd does not make this assertion. Additionally, as of January 25, 2012 such a relationship between the species had not been established (personal communication, Corey Kallstrom, U.S. Fish and Wildlife Service, Southern Nevada Field Office.) On page 25, table 5, the author listed Adelpha bredowii, Callophrys johnsoni, and Colias philodice among the common butterfly species sighted during the project.
