Aeviters (Japanese: ティダーラ, Tidāra) are Insectoid creatures in Xenoblade Chronicles X. They are almost always found dormant, and will attack if approached. They can be found in Noctilum and Sylvalum. They are similar to Ictuses.


"Enduring insects that survive by absorbing ether from the atmosphere. Due to their intensely long lifespan, they mate only once every dozen years or so, and will often stop moving altogether in order to conserve energy."

"Before reaching maturation, aeviters live underground, feeding on the sap from tree roots and other organic matter they encounter. Though generally docile, they are also quite territorial, and will attack anything that encroaches on their ether-harvesting grounds."
