My daughter nearly stepped on these while walking her dog through a recently mowed field. I have scrolled through your bug links until I am dizzy and cross-eyed. Can you tell me what they are? They seemed to be feeding on a small dead rodent, possibly killed during the mowing. (Notice the hitch-hiker flies.) Thanks.
These are Sexton Beetles or Burying Beetles. They will bury the mouse and lay eggs on it. It just seems odd that there are so many at work as they generally work as a couple. We believe these are Tomentose Burying Beetles, Nicrophorus tomentosus.
