Found most often in the ears, between the toes and on the backs of dogs. After feeding they retire to baseboards, molding, around window-cord pulleys, any protected opening. Adults are flat, and uniformly red-brown with tiny pits scattered over the back. Unlike the male, the female enlarges after eating. The enlarged portion of the body becomes gray-blue to olive in color.
