Cosmos spawn mostly in the blue area, but also sometimes in the green area by portal and the river, if you see one hanging down you can enclose it with walls and a roof to trap it. As of 9/6/24, having chitin in your inventory and feeding it a plant species Z seed will automatically tame it once it dances. The intended taming mechanic is you wait for it to run, then it’ll play a game of red light green light with you, when it shines green run towards it, when it shines red, stop moving. Keep doing this and feed it chitin. After every feed it’ll run away and restart the game. Keep doing the game until it’s tamed. Once it’s tamed, it eats plant species Z seed. You can use it as a semi grappling hook, it won’t let you reel in but you can build momentum and swing like a pendulum. It’s other mode (R on PC) lets you fire webs at dinos to slow them down. As a shoulder pet it also automatically shoots webs at attackers. Send this to the top to help people see!

For taming- walk up to him with a light pet with no aggressive creatures around & wait. After a few seconds he'll do a little dance & you can feed him.

At thd moment, Plant Species Z seeds are the best, but he will eat chitin in a pinch. Once he eats, he'll run off & use his glowing body to play a literal game of "Red light, Green light".

Stay still on red, run to him on green- be prepared to put your brakes on though- If you continue to move on red, it will reduce the tame effectiveness & he'll also attack you/any dino in his radius, including wild ones, so be careful, because those dino WILL attack your potential tame as a result.

Once you get up to him, feed him & he'll run & you play the game again. Rinse repeat til tamed! GL everyone 😄

Best way to find one is with gene scanner if your not a high enough lvl to get gene scanner then look for webs and webbed Dino’s. If you’re planning to go to red or blue zones then I would recommend a normal light pet over this guy i also recommend the outlaw hat skin to put on it

When you first encounter it it will be peaceful feed it Plant species Z seed and or Chitin. Once you do this it jump around then crest a webbed mound where he or she will flash red or green for a game red light or green light. When it is green run up before it turns red. If not just crouch just to be safe, then wait for it to be green again. Then rinse and repeat if necessary. If you mess up it will attack you for like 2 seconds then just wait for it to mound up again.

After you feed it when it’s green, runaway a little bit as fast as you can and the spider will often stay in the same spot.

Depending on the area you encounter them, they can get stuck trying to get away from you to continue the red/green game. The taming progress slowly depletes in-between feedings, so the faster you can give em some space and get the lil guy lighting up red/green again, the better.
