Grub
by: Trina

Looks like the ever pesky Japanese beetle to me. I live in Alabama and every spring when we are getting the garden ready to plant, we dig up several of these. They start coming out of the ground here as beetles in June. Chickens love 'em.

We do not know which Scarabaeidae grub Amanda had, since we did not have the grub in hand.

The ones in your yard, may be the sugar cane beetle...they are all in the Scarabaeidae family of beetles. These grubs all look similar in a photo.

Sugarcane beetles live in eastern US from Oklahoma and Kentucky southward, so that must be the area where you live. Amanda, who sent the photo in, was from CA, so it is NOT the sugarcane beetle grub in her soil.
As I commented originally there are many scarab beetles in N America...around 1400 species.

Glad you found out which one is in your yard.
Larvae

I have these everywhere, and after research and professional confirmation, I found that it is the larvae of a sugar cane beetle. Search sugar cane beetle larvae on google images and you'll see pictures.

This grub is the larva of a beetle, so technically it is not a caterpillar. We usually call larva of butterflies and moths caterpillars.
Beetle stages of life are egg, larva (in this family of beetles - Scarabaeidae the larva are called grubs), pupa, then adult beetles.
They are common in soils as they eat plant roots and decaying organic matter.

You did not say where you found these grubs? Or why you are worried...they do not bite??
As mentioned below in the comment section, these are grubs of some sort. Here is the bugguide site to see the various images - http://bugguide.net/node/view/187/bgimage
There are 27,000 species of grubs in the world.
Without a photo of the rastor patterns and closeup of the insect or have the insect in hand it would be hard to id. It may have to be keyed out which is viewing under a microscope to look at legs, rastor patterns, face, mouthparts, etc.

Larvae typically feed on decomposing matter: dung, carrion, etc. Some live in soil and feed on roots--some of these are agricultural pests.

You could take the grubs to your local extension service for identification.
Here is more information about grubs that infest lawns.

You have grubs in your soil. Not sure which grub you have. The adults are most commonly called June beetles...tho there are many adults that provide grubs in our lawns that are pests.
These would include but not limited to - June and May beetles, Japanese beetles, Northern masked chafers. Most grubs in the Scarabidae family feed on roots of plants....mostly lawn grasses especially bluegrass.

These grubs can be identified by looking at the patterns of the rasters (hairs) on the rear end. Then you know if you have a pest grub or just an incidental grub.

This is a common grub usually found in the ground and in my garden where it feeds on various root crops. They will mature into some variety of beetle as an adult.
