Some sort of grub I guess. I'm clueless about bugs and their larvae forms and what they like to eat. So I have no idea. I still don't know what it was that was causing the damage to my semps for years in the CA semp bed. Seems like a lot of critters were identified to be those eating dead plant material but never an identification of what caused the damage to the main root stems of so many of my semps. It just got to the point that whenever I found a semp that pulled out of the ground real easy, I would just take the head, clean it up and place it back onto the ground hoping it would root again. A few did.
