Large Grub Inside Rotten Felled Tree #740781

Asked March 25, 2021, 6:42 PM EDT

I was curious as to what type of insect this grub will turn into or if it is endangered. For now I have placed it in a dark container with pieces if rotten wood similar to what it was found in. The grub is about 3 inches long and 1/2 inch in diameter

Hi, It is a species of white grub. Did you find it in rotten wood or was it in the soil?

It was about 7 feet up on a large rotten portion of a tree.  The tree was felled only a day ago.

Then it is most likely the larva of the Eastern Hercules Beetle, the adult is the largest beetle found in Virginia.
