Remarks: Dermacentor variabilis is the most common tick on dogs and humans in Nebraska , known from all regions but the northwest panhandle, with larvae and nymphs occurring in high numbers on deer mice, Peromyscus , especially in “river bottom woodlands,” and can be found in association with other tick species on the same host individual ( Rapp 1955 ). We collected 14 adults from humans, and nymphs from many small mammals, especially Peromyscus spp. , O. leucogaster , and M. ochrogaster . The raccoon ( Procyon lotor (Linnaeus, 1758)) and Virginia opossum ( Didelphis virginiana Kerr, 1792 ) are the principal hosts of the adult stage of the tick in Missouri ( Kollars et al. 2000 ). The type host and original locality of this species are not known ( Cooley 1938 ).
