I would like to propose to the Hollow Knight fandom: what if Hornet/Weavers AREN'T based on venomous spiders. I draw this mainly from the fact Hornet needs the Pollip Pouch to use venom. If she had venom of her own, you'd think she wouldn't need a distinct tool for it. Further, no aspect of the weavers that we know of references venom in any way. They aren't called venomous, and they all seem to explicitly have their faces/mouths covered from creation, which would be weird for a creature that benefits from biting.
Now, you may want to tell me that's less interesting, but I would like to clarify, non-venomous spiders are an extreme minority, there's only 2 known groups of spiders that lack venom glands (the second one is complicated). The family Uloboridae and maaaybbe the genus Heptathela (I've seen conflicting reports, and from what I am able to find, it's possible their venom glads might just be small, and the spiders themselves seem pretty understudied). I'm going to put aside Heptathela due to the lack of research accessible to me, and focus on Uloboridae.
Uloboridae spiders, also called cribellate orb weavers, are bizarre little guys, ranging from "yeah that looks like a spider I guess"

To "I mean, I guess, but it looks a bit off"

To "Absolutely not no fucking way"
(Photo by Peter Webb, of a "Miagrammopes brevicaudus" which I refuse to believe is not just a stick).
As you can now clearly see, these spiders are Weirdos, and I would like to focus on a specific genus, Philoponella, and somewhat specifically Little humped spiders (Philoponella congregabilis), a name given to some really unique Australian spiders, which are not only venomous, but build communal webs! An extreme rarity among spiders. Let's take a look at one.

Not only that, but these spiders tend to build messy, sloping webs communal webs. Not unlike what we see in both Pharloom and Deepnest. Webs just sorta strewn about. Built layer by layer. Notably, these spiders also do not remove their old web when they make a new one, with some sources I could find suggesting they're incapable of ingesting their old silk. Further, from at least one observation I could find in Australia, spiderlings appear to both receive some level of maternal care (specifically built webs and some level of food sharing) and at least some appear to inherit their mother's web, building on the old webs left behind.
Interestingly, these spiders kill their prey via constriction using their silk. They wrap the prey so firmly, the exoskeleton is crushed and the prey is killed. Doesn't death by constriction sound familiar? It's how the First Sinner was killed. The only weaver we know of to have been sentenced to the Slab. How fitting that she would die the same way weaver's might've killed prey.
So my proposition is, what if Weavers are based on something like these guys? Communal web weavers, lacking venom, crushing prey to death with silk. Not ingesting their own silk, but leaving it literally everywhere instead. Taking care of their (rare) young, and leaving behind nests to be inherited. A weaver's bite isn't one to be feared, it's quite literally their weaving you ought to be afraid of.
