The general life cycle of clerids has been known to last anywhere from 35 days to more than 3 years, ... 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. The complete life cycle of a cheese skipper in appropriate nourishment and temperature conditions can be as short as 12 days (1 day for egg development, 5 day larval maturation, 5 day pupal maturation, 1 day of adult feeding before reproduction). This knowledge is especially needed in countries with high levels of criminality and where the arthropod fauna is still under-recorded and not well known, such as Angola. Female lays up to 30 eggs per day in cracks or crevices of cured fish. Their life cycles are quite short, less than one year in most cases and many have a shorter span, either by design or predation.

They compensate for this by producing large numbers of offspring. Pig trotters were exposed to adult beetles at 21 ± 3 °C and 12:12 h day/night cycle. Both larval and adult N. rufipes have been recorded as predators of other stored product pests but are predominantly a pest of stored food, meat and animal products, such as copra, ham, dried fish, and mummies (Lambkin and Khatoon 1990). We made observations and took photographs every 4-5 days for 12 months. Female produces 200–500 eggs. Reddish brown in colour. Lifecycle. It takes as short as 32 days to complete life cycle.

The red-legged ham beetle is a cosmopolitan pest, causing significant damage to stored products such as copra (dried coconut), ham, cheese, dried fish and other high protein foods (11, 16). 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 predatory larvae feed mainly on wood- and bark … However, the typical life cycle is as follows (Mote 1914): Egg ~23 to 54 hours — Larva ~14 days — Pupa ~12 days — Adult ~3 to 7 days.
