Help Dynasties

It's entirely possible that they are just hanging out near the top for no reason, but if they stay there consistently, it's usually a sign that something is wrong, such as substrate composition, humidity, or ventilation. If you recently changed the substrate, they might not like the new sub for some reason. If they appear motionless or limp, then it means that they don't have enough air.

 
I looked at them again and they are now burrowed in the substrate.  They keep moving around the substrate, which I thought is also bad? o.o

 
What is your substrate made of?  Did you do a total substrate change, or only a partial change?  How much ventilation do the containers have, and what temperature are you keeping them at?  Are the larvae producing plenty of frass pellets?

 
I got the substrate from the Titan Monster Shop and I added some rotted wood and sphagnum peat moss.  I drilled five holes for their ventilation and put pest tape on it.  The temperate is usually around 73-77 degrees and they are pooping a lot. 

 
I've had the same experience. Don't fully close the countainer. Poke some holes on the lid. Your larvaes are going to die. They have no air.

 
My D Grantii larvae do this occasionally, and they've been perfectly okay. Not sure why grubs like to wander above the soil, but it definitely doesn’t always mean there is something wrong.
