Interesting info. Google, bald faced hornets. They actually remember people and will go after specific individuals.
Bald-faced hornets can remember the faces, and unfortunately, there is no witness protection program to guide these wasps. So, if a human inadvertently returns to the nesting area of these wasps, they will wait with all the patience and target the victim. They are known to fly to the invader’s home or nest to sting them aggressively for committing the crime.
