Moved, Elateridae larva, not Tenebrionidae...
The underside of the head, the smooth body segments and very smoothly rounded off tail all point to a type of Click beetle larva, not a darkling larva.

Moved from Unidentified Larvae.

Moved from Darkling Beetles.

Moved from Beetles.

Kojun is the teneb expert here, but I'll go with Elateridae (wire worm) just to be contrary :-)

A Tenebrionidae
This is a larvae of Tenebrionidae of some sort.

Thanks Kojun for getting me i
Thanks Kojun for getting me into the "Family". Do you recommend my tryig to "raise" any of these larvae to document their Adult ID. Have most of them already been documented, but its that they are extremely difficult to ID in their larva forms? How long does it take for a larva to grow into the Adult stage? I am particularly interested in the Ground Beetle Larvae that I got last year (a really colorful critter). I think that this latest one I found is just an older version of the same thing. What would this older (much darker & slightly larger) larva feed on? Thanks for any help & suggestions.

If it is a Teneb, it will take a while to raise, but they have low requirements. Just stick them in with the substrate you found them in. Larval associations in the literature is sparce so it now that you have pictures of the young, it would definitely be interesting to see what the adult is. If you have a series of larvae, may be good to off a couple of the younger smaller ones and preserve them in alcohol as species differences in larvae may be hard to see just in a photo.

Thanks. I appreciate the inf
Thanks. I appreciate the info as I've never tried anything like this before.
