Necrobia rufipes is attracted towards carrion in the later stages of decomposition, so its arrival on carrion can help provide an estimate for the post-mortem interval or PMI. Necrobia rufipes (De Geer, 1755) (Coleoptera: Cleridae) is an important stored-product species with world-wide distribution. Riley made the first economic investigation, citing cases of extensive inj ury to hams in St. Louis and Boston (USA).
