Swamp Cave is great when taming one of these guys, no Ghillie is required just bug repellent. Make sure you clear the area first because swamp cave is a bit difficult and bring extra sets of scuba tanks. Creatures can get up to level 200-400 so be prepared and watch out for arthropluras
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
Make 1 foundation and put 8 walls on it making a 2 high box without a lid, drop the spider into this funnel like trap, when you see it's legs show through the trap from the outside look at them directly and you can feed it, you do not need bug repellent for this
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 ;)
So, biggest thing no one tells you on here. If you only have repellant and no ghille, put it on and go at them from the SIDE!! Not head on, not directly behind. The side. Never aggros on you that way. From the back and front even with repellant it aggroed 3x each before i tried it this way.
