Realistically you're likely to have mosquitos any warm weather months of the year throughout Michigan as well as most other states in the eastern U.S. In the past couple of years we've camped along Lake Michigan and several areas of the U.P. in July & August. In 2012 while in the U.P. in mid-July we had flies in abundance in Copper Harbor. Nothing that a good fly swatter couldn't handle though. And then in Ontonagon we had hardly any a few days later. And then a couple days after that we didn't have any problems with them in Brimley in the eastern Lake Superior area.
We just came back from the state park in South Haven in SW lower Michigan and while there was a sign at the ranger station about biting flies we found no problems at the campsite nor at the beach. My experience is that while at the beach a lake breeze will reduce the flies while a breeze from the land will increase flies, but there is no guarantee either way.
It really depends upon weather conditions. If it's unusually wet and warm you'll get a crop of mosquitos shortly thereafter. If it's dry you may not see any mosquitos. I have no idea why there are flies one year and not the next. I wouldn't let the "possibility" of insects deter you from making plans for a camping trip wherever that may be. You will always hear horror stories from someone that ran into a particularly bad time period whether they were camping in Florida, Minnesota, North Carolina, or Maine. Obviously the campgrounds all around the country stay busy during the usual camping seasons regardless of any insect situations. Go ahead and plan your trip and enjoy it when you do.
