Spiders do not consciousness, or at least I have never read that they do.
But...
Would a spider know or "know" or recognize a spider web not made by itself or one of its kind? Would a spider get caught in another spider's web?
(Please, do NOT ask "ai" or search engines (I could do that myself, cmon), answer from your own experience/expertise only)
PS: Now I wonder if there are spiders that hunt in packs, I have also never seen that.
