In the spring, the nymph ticks emerge and begin their quest for a blood meal. Emergence of Ixodes scapularis and Borrelia burgdorferi, the Lyme disease vector and ... which is maintained by an enzootic life cycle typically involving Ixodes species ticks and small vertebrate hosts (Piesman and Gern , 2004). Several variations of this general ixodid developmental pattern exist. Following a blood meal during the nymph life cycle, between spring and fall, they transition or grow into adults where they seek larger hosts such as deer, moose and bears. A two-host life cycle is found in a few species of metastriate ixodid ticks, e.g., Hyalomma anatolicum excavatum: Fed larvae remain on the host, molt (ecdyse) in situ, and the unfed nymphs reattach.
