Lone Star Tick (Amblyomma americanum) lives in woodland edges across Southeastern United States. It feeds on mammal and bird blood.
Fascinating facts about the Lone Star Tick
- Lone star ticks can stay latched for up to seven days, feeding silently while their host goes about daily life. That week-long attachment gives the tick ample time to ingest a full blood meal, transmit pathogens, and become fully engorged, because the bite often goes unnoticed until the tick drops off.
- The lone star tick is a proven vector of the heartland virus; after two severe febrile cases in Missouri farmers, researchers in 2013 confirmed transmission, and six additional cases were identified in 2012-2013 across Missouri and Tennessee. This shows the tick can spread emerging viral diseases beyond its well-known bacterial pathogens, expanding public-health concerns in its range.
- A bite from a lone star tick can trigger alpha-gal meat allergy, a delayed reaction that appears 3-6 hours after eating red meat and can cause life-threatening anaphylaxis. Researchers found alpha-gal molecules in the tick's saliva in a 2019 study, linking the bite directly to the immune response that makes ordinary meals suddenly dangerous for sensitized people.
- A single female lone star tick can swallow enough blood to weigh about 0.63 g, and then lay an average of 5,873 eggs before dying.
- Eggs laid by lone star ticks hatch after roughly one to two months, depending on temperature: a 1973 meadow study recorded hatching in 31-67 days, while 1974 eggs emerged in 40-55 days.
