Judging from the length and width of the larva, I believe that the host is a Lepidoptera larva.

Thanks for the shooting advice, but I have just returned with additional images. Shooting was difficult due to area being in very low light.

Great! Looking forward to more images/info.

In the meantime, I would recommend using a tripod or similar implement (e.g. small beanbag) to stabilize your camera for your next round of images. The EXIF data on this photo tells me you’re using a Panasonic DMC-ZS8, which was set to 400 ISO and used some amount of image compression. See what you can do to set the file quality to max (zero compression) in the menu settings, and bring down the ISO to 100 or 200. If you’re fluent enough in your camera to shoot in manual mode (always preferred, especially for macro), you can also adjust your shutter speed and aperture settings, which will allow you to work the “Exposure Triangle” to your maximum advantage.

I have not excavated the specimen. I should have a chance latter this afternoon. There were two specimens growing within a couple of inches of each other.

there was a larva attached to the bottom of this. Did you excavate a host?
