Large White Grubs

Question

I mulch between garden plants with grass clippings. Last year I saw some large white grubs in the garden. They were easily over an inch long and about 1/2 inch in diameter. I also saw holes of the same diameter on the soil surface, and assumed these were from the grubs. I saw small clumps of fresh grass clippings pulled down into these holes. Do grubs do this? If so, what kind are they, and do they do any harm to garden plants or the lawn? Thanks for any info.
