@MadeMeSmile Sorry, but I cannot find any reference to a Japanese Bee Fly on Wikipedia.
Do you have a link to a naturalist or scientific website that describes the species?
@sohkamyung Oh look, this post is 4 years old, maybe it's not AI after all:
@scy Ah. That Reddit post references this article in the Journal of Geek Studies [ https://jgeekstudies.org/2018/10/12/entomological-diversity-of-pokemon/ ], which features a photo of this particular bee fly, Anastoechus nitidulus.
So, I also consider it to be legitimate. 🙂
