Deer tick A tick with a 2-yr life cycle, and 3 feeding seasons; the cycle begins in spring with soil deposition of fertilized eggs; by summer, larvae emerge and imbibe a blood meal from small vertebrates–eg, white-footed mouse–Peromyscus leucopus which may be infected with Borrelia burgdorferi–maintaining the spirochete in the tick population.
