Minecraft wiki entry for Evoker, associated text: Evokers attack players, adult villagers, iron golems, snow golems,‌[BE only] and wandering traders within 12 blocks by waving both of their arms while looking at their target and summoning evoker fangs or vexes. They are neutral toward every other mob except illagers, which the evoker is passive to, even when hit by one. If a llama, a wolf, or another hostile/neutral mob is caught in the attack, it retaliates on the evoker, causing the evoker to be hostile to them.
