At a glance

A two-host tick feeds as a larva, moults to a nymph on the first host, then drops off after the nymphal meal and later finds a second host as an adult. This detail belongs within tick life cycle. Species, life stage, climate, host and region can change what is observed, so one example should not be treated as a universal rule.

Key takeaways

• A two-host tick feeds as a larva, moults to a nymph on the first host, then drops off after the nymphal meal and later finds a second host as an adult.

• This detail belongs within tick life cycle. Species, life stage, climate, host and region can change what is observed, so one example should not be treated as a universal rule.

• Reliable identification and interpretation combine several observations; appearance or one field sign alone is rarely enough.
