what do we consider limits for bug? Is just true bug bug? Is just insect bug? What about other arthropods, like lobsters and millipedes and scorpions? Do barnacles count too? Then what about tardigrades and velvet worms? What about snails and slugs? If slugs and snails then do clams and squids count? Obviously earthworms are bugs then, but are all worms? What about planarians and nematodes and all the other wormies??? Do lampreys count then? Where does it end?????? Where do buggies ends? Are armadillos bugsses? Are hummingbirds? Are we? Waow, modern philosophy is fascinating.
It's arbitrary since "bug" can mean all kinds of things depending on who you ask. For my blog, I include insects, arachnids, myriapods, woodlice/terrestrial isopods, terrestrial annelids and terrestrial flatworms, velvet worms, and terrestrial gastropods. Maybe a few other things I'm forgetting. I don't include marine inverts, or microscopic stuff.
