Dear Bevill JB,
This is not a caterpillar.  It is the Grub or immature stage of a Scarab Beetle.

Dear Daniel…
That is so fascinating.
Thank you very much for responding. This is a  simply wonderful and most educative site I have seen in ages.
Best regards,

Found this in my firewood. It is a little more than one inch long. Thought at first it was some kind of tapeworm. What could it be?

Dear PJ,
This is a beetle larva in the family Buprestidae, the Metallic Borer Beetles or Jewel Beetles, and the larvae are known as Flathead Borers.  You can see matching images on BugGuide.  Knowing the species of wood might help to narrow down the species possibilities of the Flathead Borer.  Here is an image of Flathead Borers from BugGuide.

Hi Cori,
This is a Crawlyback, the larva of a Figeater or Green Fruit Beetle.  Crawlybacks are often found in compost piles.

so I was digging at the site of a rotten, dead tree that fell down and discovered these lil things! I thought they might be cicadas, but after looking at pictures I’m really not sure.

Dear Stolz,
These are not Cicada Nymphs, but rather beetle pupae.  They are most likely Scarab Beetle Pupae.  The larvae of some Scarab Beetles feed on rotting wood, and they will pupate in the immediate vicinity.  You can compare your images to this image from Insect Images.

Subject: What type of grub is this?

We found this grub burrowed in the middle of a frozen dead ash? tree we knocked down. We were cutting it up with an axe and noticed a few of them. The inside of the tree was totally eaten and was full of dark brown casings/guano. The fat big grub was right in the hard wood in a self made hollow.
We thought ands were damaging our trees but maybe this is the culprit! What is it? Any information about how to get rid of it, damage it causes, etc? Pretty gross but pretty cool at the same time. Thank you

Scarab Grubs

Scarab Grubs

We believe these are Scarab Beetle Grubs, most likely Rhinoceros Beetle Grubs from the subfamily Dynastinae.  We do not believe the Grubs are responsible for the demise of the tree.  They will infest dead and dying trees that are beginning to decompose, but they will not kill healthy trees.

What’s That Grub?

Hi Laetitia,
This is not a Caterpillar, but we do believe it is a larval insect.  In our opinion, this is most likely a Beetle Grub, though we would not rule out that it might be a Sawfly Larva.  While your individual looks very different from the larvae in the links we provided, we wanted to show you some examples of possibly classifications.  Knowing the plant this larva was feeding upon might help with the identification.
