Not unexpectedly on bones but of what ? Not human I hope. This is an important species in forensic entomology. You both may wish to read "What is the edge of a forest?

Hello Robert,
Not human of course, the same bones as in my thread with Piophilidae (of a cow I believe, but these may well be of a pig simply because cattle stock is many times smaller then pig stock here).
