Impregnated dino eats constantly and slowly loses hit points. Have plenty of food in inventory and a snow owl to top up health until it's ready to give birth

In my experience, my impregnated creature would not eat food on its own while I was away on another map gathering things for its cravings, or when I logged out even if the food was in its inventory. I had to force feed it to get it back to full. However, while I was there on The Island it would eat on its own. Just a heads up!

I just got a pheromone from a female on The Island. Wasn’t expecting it due to every other comment saying it needed to be from a male, but I guess it’s possible.

When I killed 1 It did not drop the thing to tame 1 what do I do

Some tips I'm going from my experiences today.

Take a Fob to defend yourself (Heavy and generator boxed up) while incubation happens

Have everything pre-made that it can ask for

Have a sinomacrops for the quicker perishables such as honey

Someone already posted a list of possible cravings, kudos.

Net gun is a must net whatever the female is fighting and then net her, kill off all distractions/threats then damage her

Use an assault rife and magnifying glass to gauge her health

If you are trying to find one by sound you wont find it. They do make helicopter sounds but it is very quiet compared to what you think it would be.

When killing one of these get a couple flying creatures that can really take a hit like a griffin or something. Also when trying to tame one of these you have to impregnate a Dino but before you impregnate a Dino you have to get the rhyniognatha to at least 100 HP then let it mate with a large dinosaur (I used a Rex) after force feeding the orb to the large dinosaur you get after killing a rhyniognatha. Then the rhyniognatha will leave you alone and you have to care for the impregnated Dino and give it all its cravings. After almost an hour your impregnated dinosaur will die unfortunately, and you have a juvenile rhyniognatha and then it’s like raising a regular baby Dino

It would seem feeding your Dino the requested food will make the timer jump forward a bit

Ok, to the guy who said you net it and now it won’t impregnate your rex, have you fed your rex a pheromone? That way it knows to impregnate?

Taming one. It'll take on the stats of the father randomly, just like breeding dinos. It'll be random. So there is a possibility of having a super tame with all the mutations of your super dino. CAUTION, soul balls, and cryopods cancel impregnation.

If you cryo the host the larva will die

Where can I find It? Some say in the Red Woods and some say in the swamp

You can find on lost island around where the sinos spawn just stay around that swampy regions

Do a double take to make sure that level 150 you spotted is a female. If it is male and you forget to check you might lose the dino you wanted to sacrifice l while waiting for it to lay eggs.

Hey guys I found one and I figured out how to tame one. When you kill one you gain a Rhyniognatha Pheromone and it’s used by feeding it to any creature will mark it as a host for egg laying and I found mine on lost island in the jungle 60 lat 50 long.

TAMING A RHYNIOGNATHA

So to get the female to lay eggs

Find a male

Kill

Take feremone

Find a female

Get it down to 10% health

Give your rex or dino the feremone and boom she will lay eggs in it.

`Your dino will then slowly die`

I got a 5min timer, with a craving timer underneath that, it's like a imprint buff, it asks for stuff like kibble and black pearls, I presume this will give it some sort of buff or levels to baby!

They will only lay on a host that's higher level than them

Heads up! When an impregnated creature craves Woolly Rhino Horns, it will also accept Deathworm Horns for the craving.

Also, Megatheriums get the Bug Killer buff and aggro onto Rhyniognatha.

Rex can use pheromones 100% used low level rex

WHEN DAMAGING THE BUG REMEMBER

10% SO

1000 =100

2000= 200

3800= 380

4500= 450

7800= 780

The best thing that worked for me to tame this creature was a Trike!
