Ok but "bug" has multiple meanings, and almost nobody means "hemiptera" when they say it. More commonly, it's any terrestrial arthropod. Arachnids are bugs. Centipedes are definitely bugs.

Heck, there's a broader definition that basically includes all arthropods. "Moreton bay bugs" are a popular food this time of year. And they're a kind of lobster.

uh, slugs are bugs! any non-vertibrate animal is a bug

uh, slugs are bugs

I'mma be honest, I would not instinctively agree with this.

I suggest "bug" applies exclusively to chitinous invertebrates.

I'm trying to square my instinct that

  1. snails aren't bugs (because they're squishy without the shell) with the feeling that
  2. crabs are bugs (because they'd go tap-tap if you tapped on their exoskeleton with a finger) but
  3. hermit crabs aren't bugs if they're in a shell but are bugs if they're naked

Snail shells aren't chitinous.

Crab shells are chitinous.

Hermit crabs are only partly chitinous, and the shells they use are not chitinous.

Hope that helps

I would. I think that just goes to show how informal and unworthy of policing the term is. We even call viruses bugs a lot of the time.

yeah, i would say "a bug is something that annoys you" so a virus could maybe be perceived as a bug as well, though i also would like to point out that "annoy" does not mean "i don't like it". it's like doing sports, it can be painful but also very fun
