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. Howe, R.W., 1953. Lifecycle. 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).

Their life cycles are quite short, less than one year in most cases and many have a shorter span, either by design or predation. Eggs of this species were detected on Day 2 and only 7 d were needed for completion of its life cycle. Habits. When other methods are notable to provide appropriate information, life cycle of insects plays an immense role in Postmortem interval estimation. The species completed its life cycle on the cadavers on Day 8, when teneral adults started to emerge .
