these were "swarming" on warm days in March in Calvert County Md. in the playground area of a preschool. They had recently received a delivery of hardwood mulch.

We were not able to identify the beetle in your photo. The photos were out of focus, we could not see all the identifying features, and could not get an idea of size, etc.
We suggest that you take a sample to your local extension agent, Herb Reed, for an accurate diagnosis.
