Can you help us identify the probable pest that is chewing tiny holes in the leaves of our alder tree? Brown spots develop around the holes and then entire leaves turn brown and are falling off, as we speak. We live in south part of Aurora, near Nine Mile Station. We are not seeing the bugs. Images on google for alder beetle and for Japanese beetle damage don't appear exactly like our damage. Not skeletonized....at least not yet!!! See attached image We would appreciate any advice. You can call me on cell at<personal data hidden> if it is easier than writing me. Sincerely, Julie Dunsmore
