Insect and Spider Identification: CLOSED: Giant Grubs, 1 by xerichick

I'm located outside of Austin in the TX hill country and have found over 100 of these in a 5'X10' raised vegetable bed. The soil is a beautiful blend that a neighbor had purchased and hauled in from a nearby nursery early this spring, but the grubs are probably larva of neighborhood beetles. I discovered them in Sept as I was cleaning out old greenbean vines and turning the soil to get ready for a fall planting. They are almost 3 inches long and about almost 1 inch wide with brown faces. I have seen some chunky girthed 2 inch long brown beetles in the yard before and assume that they are good for breaking down organic matter but wonder if they are harmful to actively growing vegetables in the bed. Even though I did a pretty thorough job of turning the soil, I'm sure I must have missed some of the grubs in there. Right now I'm growing garlic in that bed.
