Tranq it and you can do damage to it and check with a magnifying glass to see if it’s below 10% then when it wakes up use the pheromones and watch the magic

Yes this creature is only on the island and lost island

Best strategy from what I’ve found

1 first scout the swamp with a spyglass from the back of an argy. This will allow you to see the gender without getting too close.

2) If the bug is a male, kill it and harvest pheromones. If female make a note of location for later. For killing the male use beelzebufo or Megatherium.

3) feed pheromones to a tame with high drag weight. My personal recommendation is Paraceratherium as they are very common and fairly easy to replace. Also the platform saddle plus mini gun turret makes it simple to get a female to ten health

4) track down female and get it to 10% health. If you find yourself with multiple pheromones and multiple sacrifices you can get multiple tames implanted with eggs in one fell swoop.

5) meet creatures very bizarre food demands until baby makes its big entrance and ta da. You now have a giant incectoid assault chopper.

Carchas can incubate as well - have one player hit the Female Rhynio until she's below 10% health. During this, you ride the Carcha and feed it the Male Rhynio pheromone. When the Female is below 10% health it will automatically disengage from your friend (I assume if close enough) and start hitting the sacrifice tame. It'll have a really noticeable red cloud around the tame when the Female was successful, and then she'll fly off.

The incubation time will begin. You want a dino with a large health pool because it will start to go down as the incubation continues, and when the baby Rhynio hatches it will kill that tame. If the sacrifice tame dies before incubation is complete or if you cryo it, the incubation will terminate and progress will be lost.

I suggest having a 'box' to keep the tame sacrifice in while it incubates, because it takes some time and you want to keep the sacrifice tame safe and alive. I just did stone fence supports and then large stone walls to surround the tame. You can then cryo the baby Rhynio AFTER it hatches (explodes) from the sacrifice tame, bring it back to base, and raise it in safety.

Good luck!

Keep an eye on the host's food as it will drop faster tjan it can eat

Now that they've come out I've tested them a few times to try and see how they're tamed.

You wanna grab a tame (I used gigas), preferably with good stats and/or one you don't mind losing - and bring it to wherever they spawn on the map you're using. You should go off and kill a Rhynio (any gender) on your own first, or with said tame so that you can harvest a pheromone from its corpse. Once you have that pheromone, feed it to the tame and then go and find another Rhynio (I believe only females can infest your tames, correct me if I'm wrong!) And aggro it to your tame while the pheromone is affecting it. Keep your tame on passive and let the Rhynio do it's thing! You'll have to shoot the Rhynio while it attacks your Dino, and get it below and certain threshold of health. It'll then perform an animation as if it is about to spit resin, but will do some sort of dive/corkscrew into the tame and voila! Your tame is now infested. Your tame will receive strange cravings while it incubates the baby Rhynio, and they're strange. It can be stuff like element it wants, ranging from consumables like battle tartare to even ammonite bile and achatina paste, all kinds strange things. Once the incubation timer goes down, your tame will die and out will hatch a juvy Rhynio! They won't aggro onto you when you hatch them (at least not in my experience) so super easy to just run up and claim them!

You also can't breed them, I don't think. Doesn't let me anyway, which isn't fun.

Quick question, do yall know if I can avoid giving creatures cravings and avoid imprints. I want to tame a trike for this creature. But I don’t know if I can get it without the imprints and expensive cravings. Just for a starter rhynio. And will the rhynio be alive and adult. I don’t need it op I just can’t find an argy or a quetz to tame and all the pts on my single player are max level 30.

It will take traits from the host creature this includes stats, and colors. I'd advise using a high stat giga, or carch, with insane mutations, even a rex will do

They spawn in the swamp -Tested

Here's just some things I've learned while taming these huge bugs.

•If you don't have something like a giga/carcha to impregnate, the 3rd best option would be a Brontosaurus for best stat quality for your baby bug. Though actually getting one to the Rhyniognatha will be quite difficult as you can't simply cryopod it and throw it once you found your Rhyniognatha (as of the Cryofridge and cryopod change in ASA). So you may need to walk it through the entire swamp...

• Keep your shoulder pets passive! This won't affect you if your using a large dino such as those listed above, though if using something smaller (though this is not recommended, most smaller dinos can't even consume the pheromone), you need to have your shoulder pets on passive so they don't attack the Rhyniognatha. I once did this mistake, and as I was going to feed my dino a pheromone, my otter on my shoulder killed the Rhyniognatha as it was on Attack Target.

•Final one, be fully prepared! Bring your pheromone and your creature your willing to impregnate before searching for a Rhyniognatha. This is because these guys love to aggro absolutely everything and get themselves killed, so if you went back to stock up on everything you need once you found one, chances are it is already dead.

Wish you luck!

You don't need to incubate at random dangerous places. Just place your host at your base and then aggro rhyniognatha with high level and mov speed sometime it will distracted but you have to agree again until your reach your base and make sure other dinos are passive and then proceed further and this way you can focus on cravings more efficienctly

Don't have your dino eat the Pheremone and the cryo it. I tryed doing this and It lost the pheremone effect (to my knowledge).

In terms of baby stats:

This has to be looked at as a Mating of your Host creature and the wild female Rhyni you getting the baby from rather than regular taming. Which means like regular breeding the baby can inherit stats from either.

The requrements to inherit the max amount of stats from the host (apart of the usual breeding chance to inherit stats from either female or "male") seems to be at this point:

-fulfill all carvings

-use either a giga, caracho or bronto as host creature

failing to do so reduces the posiible stats by a fairly high %

Only 2 will spawn on map at a time. Spawns are along the swamp River just south of the redwoods. Kill the males and take the pheromone from inventory(shotguns work well on them). When you find a female, have a tame nearby preferably a paracetamol for your first time. Damage the bug and peck at it with a low damage weapon to get below 10%. Put your tame on passive and feed it the pheromone. The rhynio will beat on it for a little bit but don't stress, it will fly up and whip down and impregnate your tame. (If you build a trap you can impregnate multiple tames, I've done 35 dinos off of 1 bug)

Ok friends let’s began well it’s a passive tames, it is creepy and fights EVERYthing , and you must kill one and then feed its faramone too a tame of yours then when you find a other one it will put a egg in your tame

And your tame will have cravings fulfill its craving for a better rhynothia and it will rip out of your tame killing your tame 😖 and it is discouraging, these bad boys can blast out cement and can pick up diplo’s .

It’s so complicated to tame.

I don’t even want to anymore.

Hmph.

I suggest you find a nice beefy dino If you don't already have one, make sure it's carnivourus so you can deal damage to the Rhynio, use that dino to kill a low lvl Rhynio, because if it's a high level female it would save you time searching for one, once you go out and kill one lower the Rhynio to 10% this part is very tedious you can easily kill the Rhynio with a good dino, once you get it low enough, feed your dino the pheromones and when it gives your dino a quick sting and your dino has a buff on it showing the amount of time until a baby, feed it's cravings or else you'll have a extremely low level one, make sure to immediately feed the baby and imprint on it the second it comes out, good luck!

Doesn't work on tek Rex's, or maybe it's bugged

The breeding tab should inform us how long the Rhynio takes to mature to adulthood once it has been born from the host, depending on the server settings?

Taming this is like a miniboss. You deal damage and after a while the rhynio will back uo and fire sticky resign at you than repeat. Only when it is very bloody AND a female will she lay eggs.
