Default What's eating these leaves?

Just got back from a weeks vacation in Northwest Lower Michigan ( Boyne Falls / Petoskey area ). My family and I spent most of our vacation trail riding atv's. We came across several large areas, some several square miles in size where the maples had almost been defoliated. I didn't see any insects or insect dropping in the area of infestation. Here in my neck of the woods in Southern Michigan where small woodlots are surrounded by miles of wide open agriculture land I have never seen a gypsy moth or tent caterpillar damage in my lifetime, so what did this?

Not sure what did it, but that sure looks like the damage done to my woods by the forest tent caterpillar. Did you notice any small, yellowish cocoon bodies? They are often in curled up leaves or under loose strips of bark.

Forest tent caterpillars were chowing on my maples when I was up in the UP prior to the 4th. Sounded like it was raining all the time. The trees didn't look to bad, yet. Everything looked lush from all the rain. There is still water in the low ground areas where I have not seen this late in the year before.

Ah...falling frass. Don't look up with your mouth open.

As long as there aren't other stresses piling up, the trees should refoliate and do OK. You might get hit for a few years in a row. Wet weather = more fungus = fewer caterpillars.

I heard that they were bad in other parts of the Eastern UP last year but not at my place. One more thing to add to the kill on sight list. It was creepy flicking out the frass from my hat and from under my tee shirt.
