If you don't want to encounter this monstrosity, here's what you can do…

If you don't want to encounter this monstrosity, here's what you can do (assuming that you want to go north and you are located to the south): you can try to go through the jungle because there are practically no flying animals in this region of the map. I hope it will work for you because I have just taken advantage of this technique and I have successfully managed to return to my base with an argentavis!

Don't forget you guys, we can craft insect repellent to appear invisible to these guys!! This trick also works for taming Scorps or Spiders with rotten meat. Bump it to the top for those who are rusty!
If you’re trying to find it in Ragnarok (Mobile) they don’t exist there.
I was just flying near the redwoods to looks around when one of these freaks pulled up on me and my pt. I didn’t realize they were in the new mobile version so I screamed and tried to run away (it caught up) and I had to dismount my pt and run for it. DO NOT GO NEAR ANY SWAMP UNLESS YOU’RE PREPARED. THEY ARE SCARY.
Pro tip: NEVER under ANY circumstances fly a PT anywhere NEAR the swamp. Dododex says they are rare, but you can get four swarming you at once. This will save your life, controller, and pt.
Only spawn when you don’t want them to
Rare??? My ass rare... They spawn in 3-5 stack literally in redwood around swamp area... Yeah they have alreay eaten around 17 pteranodon, 1 iguana, 1 trike, 20 human and lots of my stuff hardly crafted and looted.
rare my ass, these annoying buggers are everywhere near the swamp
In ark mobile edition dont wander in swamp with a flyer they spawn in a pack and will destroy your pt/argy
So basically the swamp is a no fly zone like the redwoods all because of these oversized locusts. They somehow fly faster than a pteranodon and can shoot sap. Learned it the hard way twice by losing 2 tamed high level pteranodons.
Y’all is that thing on survival evolved as well?
