What feature dictates that *I. pacificus* surveillance data must often be tracked separately from *I. scapularis* records?
Answer
Slight but significant differences in morphology
Although *Ixodes pacificus* and *Ixodes scapularis* share the same genus, they are distinct species requiring tailored management protocols due to subtle but important morphological variations. Specialists rely on these minute differences, often focusing on characteristics of the capitulum (mouthparts) and the relative positions of body markings, to ensure accurate species-level identification. Consequently, researchers analyzing tick surveillance data must maintain separate records for *I. pacificus* and *I. scapularis* to derive accurate insights regarding pathogen prevalence specific to their respective geographic zones.
