These butterflies are known for their almost complete dependence upon Kearney Buckwheat; eating the fallen leaves of the plant as larvae, and drinking the nectar of the flowers as adults - however, the adults occasionally feed on other plant species. Like many gossamer winged butterflies, Sand Mountain Blues have a close relationship with
ant s; in this case, desertcarpenter ant s feed off a sugary secretion of the larvae - if the larvae also benefit or not is yet to be determined. Once the larvaemetamorphose into the pupal stage, rather than remain fixed to buckwheat plant, the chrysalis drops into the leaf litter at the base. Upon reaching adulthood, "E. pallescens arenamontana" typically measure anywhere between convert|10.0|mm|in|abbr=on and convert|11.9|mm|in|abbr=on. The species is not known to migrate, and in fact stays within convert|200|ft|m|abbr=on of its host plant. The lifespan of an adult Sand Mountain Blue is approximately one week.cite web|title=Petition to list the Sand Mountain Blue Butterfly as a Threatened or Endangered Species Under the U.S. Endangered Species Act|url=http://www.fws.gov/nevada/nv_species/documents/smbb/smbb_petition.pdf|author=Center for Biological Diversity |coauthors=Xerces Society ,Public Employees for Environmental Responsibility ,Nevada Outdoor Recreation Association |accessdate=2007-03-24]tatus
The Sand Mountain Blue species, "E. pallescens" has been officially classified as being vulnerable while the subspecies "p. arenamontana" has been labeled as critically imperiled at great risk of extinction. In 2004 a petition was filed to investigate the status of the Sand Mountain Blue and if it should be placed on the endangered or
threatened species lists. Currently, the Sand Mountain Blues are referred to as "rare" because of their small geographical distribution around the Sand Mountain dune. In March of 2007, severaloff-road vehicle trails were closed off in order to protect the species and its host plant from intrusion.cite web|title=Move to protect butterfly steps on off-roaders|url=http://www.msnbc.msn.com/id/17722427|publisher=MSNBC|accessdate=2007-03-24]References
