Here is a nice post from Ars Magisterii on all the weird ways IRL spiders capture prey. Given that giant spiders are a (particularly low level) staple of D&D games with skeletons, goblins, orc, and traps, it's always helpful to have ways to freshen them up.

I especially like trapdoor spiders because its a nice way to combine pit traps and giant spiders.
