Lone Star Tick - Amblyomma americanum

Overview

The Lone Star Tick is distributed from central Texas, eastern Oklahoma, north to Missouri, and eastward in broad belt across the southeastern United States. Along the Atlantic coast, its distribution extends northward to coastal areas of New Jersey and New York.

Lone Star tick - Amblyomma americanum

The Lone Star tick is found in wooded areas, especially young second growth forest with dense underbrush, but it is also found in scrub, meadow margins, hedge rows, cane breaks, and marginal vegetation along rivers and streams.

Amblyomma americanum adults are well-known to feed on large mammals, especially bovine and deer, like the white-tailed deer.

Each female produces 3,000-8,000 eggs, which are deposited under leaf and soil litter in middle to late spring.
Adult numbers peak in May and decline until the end of June.
Low humidities and high daytime temperatures restrict the occurrence and activity of these ticks.

Its role as a vector of disease in dogs is uncertain, but Lone Star ticks infected with the agents of Rocky Mountain spotted fever and Lyme disease occur in nature. It is suspected in transmission of tick paralysis in dogs. Lone Star ticks transmit Tularemia (hunter's disease) to humans.
