Bug is a kid’s term for bug-like things. That’s as closest to a scientific definition you’ll get. It’s like trying to precisely define creepy-crawlies.
Case in point: the children’s movie A bug’s life. There’s a spider and two rolie-polies in the main cast, along insects (not sure all are in the Hemiptera clade).
Bug is not even a scientific definition. If I want to group spiders with bugs, that’s perfectly fine.
Doesn’t “bug” refer to the order Hemiptera in entomology?
