Need help with some immersive details

I am running one of my first ever campaigns as a GM, and I am running heavily inspired by the world of Hollow Knight. What that basically means setting wise is everyone are bugs of some sort (or perhaps a couple snails and the like). Not like “there’s a human sized world and we are at bug level”, but more like a fantasy world where the humanoid creatures are bugs. To give a better sense of immersion and such, I’m looking for ways to “Buggify” the world around, like figuring out what sort of things could be monsters/creatures/livestock/etc? What might be the types of foods and such that they might eat? I’ve thought of large slugs being somewhat like cows, but any other things like that would be super helpful, if you have any ideas of how things might be in a world like that, please do drop them below!
