Red and Black Burying or Sextant Beetle Nicrophorus Sayi
Burying beetles or sexton beetles (gensus Nicrophorus) are the best-known members of the family Silphidae (carrion beetles). Most of these beetles are black with red markings on the elytra(forewings). Burying beetles are true to their name- they bury the carcasses of small vertebrates such as birds and rodents as a food source for their larvae. They are unusual among insects in that both the male and female parents take care for the brood.
I have never spotted any on dead carcasses but see them a lot on old logs that have Shelve Mushrooms.
