K. Reeves, L­2979. In eastern North America, this louse is a host specific parasite of the gray squirrel ( Kim et al. 1986, Durden & Musser 1994). Durden (1980)found this louse to be abundant on  S. carolinensisin central Tennessee but the above record is the first one for the GSMNP. Several genotypes of undescribed  Bartonellahave been isolated from this louse (Durden et al. 2004).
