Beatle Larvae- Curl grub.

Yes, it's a beetle larva, and I believe you've also captured a tiny white springtail on it as well (tiny white thing near the "top" of the larva with two tiny antennae), and the millipede off to the left. It's likely some type of scarab beetle and reminds me of Japanese beetle larvae, though it also looks like those of chaffer beetles and "june bugs". http://www.extension.iastate.edu/CropNews/2009/0630hodgson.htm They live down in the earth and eat roots. http://pestcontroloptions.com/grubs/natural-lawn-grub-control/natural-lawn-grub-control

It is a beetle larva. Can't tell which beetle though.
