Engorged adult hard tick (A, dorsal aspect, and B, ventral aspect) found on the patient, identified to be of Ixodes species based on the inverted, U-shaped anal groove anterior to the anus. Due to the missing mouth parts, identification to the species level was not possible; however, Ixodes scapularis may be inferred given the travel history to New York.
