Blacklegged Tick or Deer Tick, Ixodes scapularis Say (Arachnida: Acari: Ixodidae)

In the United States, the blacklegged tick, Ixodes scapularis Say affects the greatest number of people for threeprincipal reasons: their geographic distribution coincides in the northeastern United States with the greatest concentration of humans (Miller et al. 1990); spirochete infection rates are high, often exceeding 25 (Burgdorfer et al. 1982, Anderson et al. 1983, Magnarelli et al. 1986); and the geographical range of the tick is spreading (Lastavica et al. 1989, Anderson et al. 1990, Godsey et al. 1987, Davis et al. 1984). This document is EENY-143, one of a series of Featured Creatures from the Entomology and Nematology Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.
