They emerged in my region (brood IX) last year, but I never got up the nerve to try eating them. For some reason, they didn't swarm (visibly where I could grab some) in huge numbers where I was at, though I could hear them all around, so all the time I kept telling myself (chickened out) there aren't enough of them to make it worthwhile. Then when I thought it was now or never, the season was closing. Maybe in another 16 years I hope to get enough courage. They're just so freaky looking with their bulging eyes.
There are some great YouTube videos about how to prep them--- boil in a pot, drain, pick off the wings if you prefer, then add to sauce, etc.
