beetle grub

beetle grub
Dixon, Phelps County, Missouri, USA
August 30, 2006
Size: 1"
Found under a rotten log. The closest I found was Synchroa Bark Beetles (Synchroidae), but couldn't get all the pictures to load. How would I go about keeping this grub and a second I found tonight until they develop? I would assume dirt and wood, but is there anything else that they need?

This is a tenebrionid - not at all sure who.

Moved from Beetles.

How did the rearing experiment go?
I'm moving this to the superfamily level for now.

You can set up a small container with soil and a chunk of rotting wood for this grub. The key to keeping it alive and growing is moisture, so don't let it dry out. A light misting each day should do the trick, but it all depends on how much ventilation your container has. Airflow is important, yet can dry things out quickly, so just keep an eye on it. You can also add a small piece of soft fruit (melon, apple, etc.) every couple of days. Your little one will probably nibble on it.

I have the moist soil (I have one of the small plastic "critter keeper" goldfish bowls, so it is well ventilated. I put some aquarium gravel in the bottom and filled to the top of the gravel with water, then covered with dirt and decaying plant matter from under the log where I found him and the second grub. I will keep it misted and offer the fruit (thanks for the advice) but he and his companion grub have already burrowed to where I can't see them. How long does it take for them to mature? Just asking since I can't monitor their progress without digging them up and would prefer to disturb them as little as possible.
