Hello Dale
Without a picture, of course, we can only give you some of the possibilities. Here is a bulletin with a couple of the most likely white caterpillars seen in autumn.
The following link is to a commercial site. MSU Extension does not endorse or validate any of the information, products, or advertisers on these sites. However, there are several good pictures of white caterpillars here with which you can compare. Some of these caterpillars may not live here in Michigan so, if you think one of them matches what you saw, you should do a little research and see if that particular caterpillar actually lives here in Michigan.
