Generalized distributions of the Gulf Coast tick, Amblyomma maculatum (pictured), a human-biting tick species newly established in the northeastern United States, in 1945 compared with 2024. Establishment was defined as >6 ticks of the same life stage identified within a 12-month period or ticks of >1 life stage identified within a 12-month period. Data from references 2–9, https://www.dep.pa.gov/Business/ProgramIntegration/Vector-Management/Ticks/Pages/default.aspx, and https://www.in.gov/health/idepd/zoonotic-and-vectorborne-epidemiology-entomology/vector-borne-diseases/tick-borne-diseases/amblyomma-maculatum-gulf-coast-tick/#Geographic_Distribution.
