Beetles found on tree
I found these two beetles on a white oak tree in my yard. It looked like they were attracted to the sap but not sure if they bored a hole or it was just releasing it on its own. Their was an old injury to the bark just above. Any info would be appreciated as we do have Oak Wilt around the area. Thank you.

The beetle in the first image is a Margined Carrion Beetle. The second beetle is a Glischrochilus (sap beetle). Below are links to information on both of these beetles. Their presence would not signal Oak Wilt. If you are noticing decline in your tree I would recommend calling a local tree care company and having an arborist come evaluate it. https://uwm.edu/field-station/margined-carrion-beetle/ https://extension.umn.edu/yard-and-garden-insects/sap-beetles
