I started a separate thread on the wildlife forum for this, but thought I'd plunk it in here for the locals. ugh!
The emergence began yesterday in Lake County, IL. There are hundreds more today. I expect thousands more soon. Last night's new reports told of people shoveling their driveways with snow shovels to remove the shells and dead males with counts in the billions (with a b)! The forester also indicated that the noise level will become so loud that two people standing four feet apart will not be able to hear each other speak without shouting as loudly as they can.
I don't hear any singing yet, but these are ugly, ugly looking creatures.
