The predatory larvae feed mainly on wood- and bark … Female lays up to 30 eggs per day in cracks or crevices of cured fish. Adult is around 3.5–7 mm in length. They compensate for this by producing large numbers of offspring. This study provides data for PMI min estimation using N. rufipes. Concerns about this pest are exacerbated by the lack of information about infestation modalities in pet food, while specific monitoring tools are missing. Lifecycle. In the laboratory we studied the taphonomic marks that Necrobia rufipes (Cleridae) can produce. Adults: 3/16" in length. Adult 3.5-7 mm Shiny, metallic blue-green or black with reddish legs Pupa (if applicable) Type of feeder (Chewing, sucking, etc. Fifty percent of fly larvae collected for 15 min were reared to adulthood to aid in identification. Female lays up to 30 eggs per day in cracks or crevices of cured fish. The ham beetle is the most important of the insects which infest meats which have become dried to some extent by evaporation during long storage or as a result of prolonged smoking. Necrobia rufipes is known to be a late inhabitant of corpses and feeds on dry cadavers (also on mummies and ham) and probably Case 4: Red Pupae on the Corpse of an Alcoholic on larvae of other arthropods. The species completed its life cycle on the cadavers on Day 8, when teneral adults started to emerge . (Necrobia rufipes) Appearance. Saved by Truly Nolen Pest Control. Riley made the first economic investigation, citing cases of extensive inj ury to hams in St. Louis and Boston (USA). When other methods are notable to provide appropriate information, life cycle of insects plays an immense role in Postmortem interval estimation. 3.1 Necrobia Necrobia rufipes is a beetle of the family Cleridae and is the commonest species of Necrobia found on cured fish.
