Lone star ticks, Amblyomma americanum comprised a significantly greater proportion of total ticks flagged on eastern Long Island and Fire Island, New York, in 1986 and 1990 than in samples reported by other authors from the 1940s (when A. americanum was not collected by flagging or from hosts) and the 1970s. Therefore, population densities of A. americanum apparently have increased in recent years on southeastern Long Island, where this species now is distributed widely.
