What are you talking about? Wasps? No, regular wasps won't be dealing actual damage to humanoids. But giant wasps will. Monstrous/giant vermin are essentially as realistic as dire animals.
Animals can indeed make up swarms. Check out the swarms of bats and rats.
How animals and vermin grow to obscene sizes in D&D is uncertain. For all we know gargantuan/colossal vermin are the results of magical experiments.
None of the monstrous vermin I've seen in artwork or media look exactly like smaller vermin either. They always have exaggerated claws, giant mandibles, rougher-textured exoskeletons. Though none of this is relevent to vermin's deserved status as animals.Dire animals are not just larger: they tend to have red eyes, and always have bone-like plate on them. They are also a lot more violent, and have more muscle mass/size to match. Monstrous vermin, on the other hand, tend not to have these physical abnormalities.
You mean a 1/8th level party? There is nothing threatening about these animals. A rat does 1 damage with a bite just like a hornet might do with a sting. And again, there's nothing relevant about it.these monsters can also challenge a party to some degree by themselves
Sure, maybe in your very specific campaign, vermin may have something that makes them distinct from other animals. My campaign might have something that makes bears distinct from all other animals. In that case I would change the bears' type to match the campaign, but not as a general rule.Maybe in another campaign, but in mine they work in the opposite process of dire animals and dinosaurs. While dinosaurs and dire animals are archaic beasts who are slowly dying out (in most cases), giant insects are actually a new genetic offspring (can magical radiation cause genetic changes?)
And my point is that thinking is completely subjective. Why should some spells not affect some critters when they're made of the same stuff - just because those critters FEEL different? (Besides balance reasons, which isn't an issue here.)You guys are still missing the point. Vermin may be animals, but they don't FEEL like animals.
Keep in mind fish (chordates) evolved from segmented worms.For an answer to the squid problem, squids and segmented worms grew out of 2 different evolutionary tracks, one having developed segmentation, the other not
"Most small mollusca." When does a small mollusc vermin (gastropod) become a small mollusc animal (cephalopod)?(a scientific definition of vermin may include the phyla platyhelminthis, nematoda, rotifera, annelida, anthropoda, and most small mollusca).

could be used for this).This is why I mentioned game balance. Humans are distinct from animals on matters of game balance, and that's it.People are also animals, yet having a type of creature combine the two is ridiculous.
They came from a common ancestor - and unless a distinct set of critera can be listed that would classify that ancestor as either animal or vermin, the two types must be one and the same.a gastropod mullusc would be a vermin, and a cephalopod mollusc would be an animal. For creatures that combine traits of both, it depends on the monster
I have yet to be convinced of any distinct criteria that would set vermin apart from other animals.
