Many people are complaining that the bees are too big, and should be downscaled. If they don't get downscaled, maybe there should a rare chance that baby zombies can spawn riding a bee, as they are similar size to a chicken, which baby zombies already are jockeys too.
I actually find that it's a perspective (as in visual perspective) thing. So when a (Baby-basically, smaller.. do they have "sizes between" ...? I can't tell) Bee is not a(n Adult) bigger Bee, it Still looks big (as opposed to bug) to me!
In fact, it multiplies its cuteness, a fair bit. And really, I can't tell the difference until I have two (at least one smaller) Bees next to each other.
Which really makes me appreciate seeing the detail on the bigger (Adult) Bees more, slightly better (because I can see it, because it's bigger). These bugs rarely stop moving (except by the - possibly small only, I think - Flowers, where they circle-around, a bit; when one's holding it: you can even see their legs, then!), and so if they weren't as-big, they'd probably seem trickier to even spot and /or even creepy-crawly.
Of course I read and /or heard here /YouTube that it's to keep the Hitboxes (which are even Larger - unusually, apparently for MC - than they are!) large-enough to counter-attack them. If they try to attack (to give the Player - other Mobs even..? - a [better] chance to hit them).
I just like that these bigger bugs (which are a-bit different from Silverfish that the Bane of Arthropods, Enchantment, works-against) aren't afraid to just be big and slow. Sleeping on it, I realized they were probably a bit more like bumblebees (which might have most with genders capable of reproduction as individuals unlike eusocial Animals [such as naked mole rats]).
