Short answer

The usual hard-tick life cycle has four stages: egg, six-legged larva, eight-legged nymph and adult.

At a glance

A tick normally needs a blood meal during its active stages in order to develop or reproduce. Timing, hosts and the total length of the cycle vary among species and climates.

Key takeaways

• Egg, larva, nymph and adult are the four main stages.

• Larvae have six legs; nymphs and adults have eight.

• Life-cycle timing differs by species and environment.

From egg to larva

A larva hatches with six legs. After feeding and developing, it moults into an eight-legged nymph.

From nymph to adult

The nymph feeds and later develops into an adult. Adult feeding and reproduction differ between tick groups and species, so a single timetable should not be applied worldwide.
