Short answer

No. Ticks are arachnids and do not have antennae. Their first pair of legs carries important sensory structures and may be held forward while they search for a host.

At a glance

Forward-pointing legs can be mistaken for antennae in photographs or illustrations. Adult ticks and nymphs have eight legs in total; larvae have six.

Key takeaways

• Ticks have no antennae.

• Larvae have six legs.

• Nymphs and adults have eight legs.

Why the mistake happens

During questing, many ticks hold the first pair of legs out in front while the remaining legs grip vegetation. From above, those front legs can resemble insect antennae.

A useful accuracy check

Educational artwork should never add antennae to a tick or count the mouthparts as extra legs. The mouthparts project from the front of the body but are not a ninth or tenth leg.
