Probably the most powerful creature on the whole island

If you wish to find these, look hard in the south cave. There is bound to be one there

They can destroy wooden structures. I was in the east underwatercave for deep SEA loot and Had a 1x1 wooden House with a bed. I had No weapon and so a lvl 200 dungbeatle Killed me nearly, Destroyer my bed and my foundation not what i expected.

On the island, I think the easiest place to find them is in the lower south cave. Go in with a longneck or a shotgun, turn left at the first intersection, kill the boas and spiders I. The first chamber, near the end of it there’s usually 1-3 beetles. Tame, and carry back to base w/ Petra. Easy fertilizer.

On Valguero, they only spawn in the scar so be careful for Wyvs but grappling hooks work perfectly in PVE if you’re alone. I used a PT for easy getaways :)

How do they have so much health for such a small thing

It usually found in caves, in the easy south cave is one of the best locations to tame them

You can find these on the center of Extinction, sometimes nearby the swamp area.
In Genesis they are also roaming around the swamp.

In Valguero I saw some of them on the bottom of a dragon nest along with Titanoboa's too and I believe Mantis too (don't remember too well) anyways I only found out because sadly ice dragons are gigantic jerks and froze me at the same time that my pteranodon ran out of stamina as I started to descend down to the lava I spotted the dung beetles before dying and losing my stuff. So if you have strong tames head to the snow zone and it should be around the edge of the top right side of your map once you see the ice dragons flying around there nest shouldn't be too far fly down and it should be there.

I have only seen these in caves so far but they are useful for fertiliser when you are growing crops and Plants Species X etc.
