Lone Star Tick Nymph

Dorsal view of an immature, or nymphal, "lone star tick", Amblyomma americanum. Nymphal ticks are much smaller than adult ticks, and people might not notice a nymph until it has been feeding for a few days. Nymphs are, therefore, more likely than adult ticks to transmit diseases to people. An Ixodes or "hard" tick, A. americanus is found through the southeast and south-central states, and has been shown to transmit the spirochete, Borrelia lonestari, the pathogen responsible for causing a Lyme disease-like rash known as "Southern tick-associated associated rash illness" (STARI). Representatives from all three of its life stages aggressively bite people in the southern U.S. Research indicates that live spirochetes are observed in only 1-3% of specimens. Persons who have been bitten by a lone star tick, A. americanum, and who develop a red, expanding rash with central clearing, known as "erythema migrans", headache or myalgia with fever, should see their physician.
