Adult Male American Dog Tick Dermacentor variabilis The American dog tick, Dermacentor variabilis , is widely distributed east of the Rocky Mountains and also occurs on the Pacific Coast. The dog is the preferred host of the adult D. variabilis , although it readily feeds on many large mammals including man. The males and females have pale whitish or yellowish markings on the scutum or dorsal shield. Males may be only 1/8 inch long, while engorged females may be as much as ½ inch in length. This tick species is known to transmit Rocky Mountain spotted fever and tularemia. view female species Tick Home   |    Tick Species
