Moved
Moved from Strawberry Rootworm. Opacicollis is listed as a Wisconsin beetle here. Moved based on Mr. Wendall's comment and Oak host.

 
Thanks for adding the guide p
Thanks for adding the guide page and for the link to the Wisconsin site.

My guess:
Something in the gargantuan Leaf Beetle Family, Chrysomelidae. I'm sure one of our beetle experts can narrow it down much further. In the meanwhile: do you know what kind of leaf it's on? A great many Chrysomelids are very specific about what kind of plants they eat, so knowing that can sometimes help to distinguish between similar-looking species.

 
Beetles were on an Oak leaf
I checked today the the leaf is from an oak tree similar to the oak leaves where I found the wasp galls. Today there were no beetles to be found.

 
If on oak...
If its on oak then it is probably Paria opacicollis. This genus's species are apparently pretty host specific. Would recommend moving to a new page for this species. Great find.

 
Thank you for the added infor
Thank you for the added information on these beetles and also for the id on the beetle I just submitted.

 
I'll make another trip up to
I'll make another trip up to the trail to see what kind of tree this was. This was up on a bluff where it is quite dry if that's any help.

 
reminds us of the beetles
we currently have in the guide under Paria fragariae-complex - Strawberry Rootworm. Sounds like it is actually more than one species. Images in the guide here

 
beetles
The beetle looks most similar to the first one shown - except for the length of the antennae. Should I move these pictures to the guide under Paria fragariae-complex or just wait yet?

 
Paria fragariae
Or you have discovered the first Chrysomelid-species ever with only 4 segments on its antenna or the antenna have broken of. I wonder why...what would have happened to the poor beetle
