At a glance

Hard and soft ticks differ in anatomy, feeding behaviour and habitat. These broad groups still contain many species with distinct regional importance.

Key takeaways

• Hard ticks belong to Ixodidae.

• Soft ticks belong to Argasidae.

• A clear upper and lower view can help identification.

Hard ticks

The hard dorsal shield is called a scutum. Hard ticks commonly remain attached for longer feeding periods and include many species encountered on people, pets and livestock.

Soft ticks

Soft ticks are more rounded and leathery and often feed for shorter periods. Some live in sheltered host environments such as animal nests, caves or rustic buildings rather than questing openly on vegetation.
