Which scientific name corresponds to the blacklegged tick?

• A. Ixodes scapularis
• B. Dermacentor variabilis
• C. Amblyomma americanum
• D. Rhipicephalus sanguineus

Answer: (A)

Focusing on which scientific name matches a well-known disease-vector helps you connect the name to real-world biology. The blacklegged tick is Ixodes scapularis. It’s a small tick common in wooded or grassy areas of the eastern and central United States and is the main vector for Lyme disease in many regions. Distinguishing it from other ticks—Dermacentor variabilis (American dog tick), Amblyomma americanum (lone star tick), and Rhipicephalus sanguineus (brown dog tick)—helps you see why the specific name matters: different species have different habitats, hosts, and disease risks, which guides targeted control and prevention efforts.
