Well, I'm gonna have to go with something more basic and say trapdoor spiders.
I mean, imagine if they were the size of a dog. You're walking in the forest and you come across a tripwire. You look up and see odd tripwires and webs everywhere, and they all lead to a strange area on the ground. So, as you back up you accidentally touch a wire. Suddenly, you feel the earth loving, and then that weird area opens up and a spider jumps out, pins you down, bites you, them drags you down under its burrow to eat you...
Yeah, that's how insects and other creepy crawlies probably feel whenever they cross paths with the trapdoor spider. But at least they're small and not some
J'ba Fofi-type thing
