If you tame this creature outside a cave(especially revival tame etc.)Creatures on every cave will still argo you, if you want to be ignored and be vulnerable(unless u don't attack any of them) against cave creatures/caves, tame a araneo/arthroupleura inside a cave, once you've tamed it, no cave creatures will attack you(unless you won't attack them).Make the arrow green so people can know this before taming it.idk if this work on pc, but works on mobile for me.:v
Cheesy tip: mount a scorpion or Arthepluora or even another Araneo, walk up to the one u wanna tame while sitting on your tamed insect and feed it. For some reason none of the Dino in game agro on insect type dinos what so ever ;)
Kill everything else in the cave but the one you want with a giga. Then approach with ghili and bug repellent on FROM THE SIDE. He will not see you and you can tame at leisure. You can stay crouched next to him.
