Weaver spider as a variant of the zombie leader for spiders

It would be a rare variant of spiders that, like the zombie leader, wouldn't have any visible change in texture.

These spiders would be born with the effect of natural webbing on their bodies but would not exhibit particles of that effect.

With each hit, she would have a chance to summon other spiders with the same effect

When killed, they would cause a web explosion, just like the effect already has. 

It would be a cool use for the effect since it seems very limited to trial chambers

(And of course... it would work on regular spiders and cave spiders.)
