Is the Asian giant hornet an extraterrestrial predator introduced to Earth to cause destruction of honeybees important for crop pollination?

This is very much the case. It is adding insult to injury, but very much in keeping with the extraterrestrial mindset knowing that it is lording over humanity in so many ways with superior technological prowess as well as their personal capabilities mentally, physically, and intuitively, at least with respect to being telepathic. To bring in and encourage the spread of yet another giant predator that will be visible and frightening to people, even as it is devastating one of the most beneficial and amazing species humans need for their survival, is clearly a match to the depravity of the extraterrestrials seeking human destruction.
