Amblyomma aureolatum (Pallas 1772)

This 2008 photograph depicts a dorsal view of a male yellow dog tick, Amblyomma aureolatum, which is a vector of Rocky Mountain spotted fever (RMSF) in the country of Brazil.Note that the back of this tick is completely covered by his hard, scutum, or shield. However, when this feature is compared with that of the female counterpart of this Ixodidae hard tick, PHIL 11069, you’ll note that the female’s dorsal abdomen is only partially covered, which allows her abdomen to greatly expand when she is ingesting her blood meal.Created: 2008

This 2008 photograph depicts a dorsal view of a female yellow dog tick, Amblyomma aureolatum, which is a vector of Rocky Mountain spotted fever (RMSF) in the country of Brazil.Note that the back of this tick is only partially covered by her hard, scutum, or shield, which allows her abdomen to expand to many times the size seen here. Compare this feature with that of the male counterpart of this Ixodidae hard tick, PHIL 11070, and observe how the male's scutum covers his entire dorsal abdomen.Created: 2008
