huge grubs inside tree

about 2 years ago, we cut down an old oak tree that was dying rapidly, and in danger of falling into the house. after debranching it, we began to cut the runk down.

inside the trunk, was not wood, but dirt. within the dirt were huge white grubs. the size of these grubs was about 4 inches long, and at least an inch and a half around. with what litle bit of the trunk was whole, id guess the tree was from 100-125 years old.

what might these grubs have been? or what would they have become? im asking because
i have reason to believe that the other oak tree on this persons property may have the same problem. it isnt in the pitiful shape the other tree was, but im noticing it beginning to decline in health slowly.

thanks, kevin

They are probably some type of borer like an elm tree borer. usually they'll pupate into a moth.

Here is a good fact sheet...http://www.okstate.edu/OSU_Ag/agedcm...ugs/f-7315.pdf

Kevin,
Look for the Patent Leather Beetle in the following link. It's the middle photo. I used this link only for the quality of the photo.

It's also known as the Bess Beetle. These guys make a very cool hissing sound.

For the life of me I can't locate a phto of the larval stage for you.
