Shiny green to bluish green in colour with red legs. Necrobia rufipes (De Geer) is a beetle, belonging to family Cleridae. In the laboratory we studied the taphonomic marks that Necrobia rufipes (Cleridae) can produce. The antennae are reddish–brown with a dark brown or black club at the tip. Reddish brown in colour. At ideal temperature (34°C and 70% RH), life cycle last around 3—4 weeks. The specie Necrobia rufipes is commonly known as the copra beetle in tropical countries and red-legged ham beetle in the United States. 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. The total life cycle lasts 36-150 days and is highly temperature, humidity and food quality dependent (Anon. Binomial name: Necrobia rufipes Common name: Red-legged ham beetle, Necrobia rufipes is a predatory beetle in the family Cleridae with a cosmopolitan distribution. Shalaby et al. Rearing containers were constructed according to Byrd and Tomberlin (2010). Eggs of this species were detected on Day 2 and only 7 d were needed for completion of its life cycle. All the life cycle occurred in the same container. Female lays up to 30 eggs per day in cracks or crevices of cured fish. 3. The upper surfaces of the body are a shiny metallic bluish-green. We made observations and took photographs every 4-5 days for 12 months. It is not a beetle which causes a constant drain on the trade, but occasionally becomes extremely abundant and a great cause of loss. Fifty percent of fly larvae collected for 15 min were reared to adulthood to aid in identification. Pig trotters were exposed to adult beetles at 21 ± 3 °C and 12:12 h day/night cycle. Some Trichodes and Hydnocera species are pollen eaters. It is beetle of significance in forensic entomology. 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. According to Nwana, 1993 and Simmons and Ellington (1925) the red-legged ham beetle is a cosmopolitan pest, causing considerable damage to stored commodities such as copra (dried coconut), cheese, dried fish, ham and other products rich in protein content. Adult lives up to 14 months. Its length varies from 3.5 mm to 5.5 mm. Howe, R.W., 1953.

Habits. The predatory larvae feed mainly on wood- and bark … This study provides data for PMI min estimation using N. rufipes. Sep 1, 2017 - necrobia_rufipes.jpg 464×800 pixels: Insect 20, Rufipes Blue, Beautiful Bugs, Blue Gleamy, Insects Bugs, Bugs N Beetles N Insects, Bugs Insects Larval specimens were collected with a forceps and preserved in 70% ethanol. Adults: 3/16" in length. Adult lives up to 14 months. Habits. 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). Moreover, it is also a forensically important insect species. Larva will bore inside the grain to continue growing. Other articles where Red-legged ham beetle is discussed: checkered beetle: The red-legged ham beetle (Necrobia rufipes) feeds on stored meats. Adult is around 3.5–7 mm in length. The life cycle varies from 36 to 150 days or more de-pending on the types of food and temperature. Females lay up to 30 eggs per day in cracks or crevices of cured fish. EGG LARVA … Concerns about this pest are exacerbated by the lack of information about infestation modalities in pet food, while specific monitoring tools are missing. 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). Riley made the first economic investigation, citing cases of extensive inj ury to hams in St. Louis and Boston (USA). Commonly feeds on dried copra and other insects that are attracted to mouldy food. First record of Necrobia rufipes (De Geer, 1775) (Coleoptera; Cleridae) associated with pet food in Brazil (Necrobia rufipes) Appearance. Marks were noted after a month. Female drills a tiny hole in the grain kernel to lay egg in the cavity. (Necrobia rufipes) Appearance. Lifecycle. The underside of the abdomen is dark blue. Flour Beetle (Tribolium castaneum) Appearance. 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. The development of Necrobia rufipes was monitored from 22 to 36 °C.. Two related species, N. ruficollis and N violacea, are only rarely found on this commodity [21]. It takes as short as 32 days to complete life cycle. 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. When other methods are notable to provide appropriate information, life cycle of insects plays an immense role in Postmortem interval estimation. 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). Recent studies on the infestation of dried fish in Nigeria by Dermestes maculatus and Necrobia rufipes with special reference to the Lake Chad District. Shiny green to bluish green in colour with red legs. Results.

Life cycle of insect act as precise clocks which starts within few minutes or hours after death. Female lays up to 30 eggs per day in cracks or crevices of cured fish. Adult is around 3.5–7 mm in length. Their life cycles are quite short, less than one year in most cases and many have a shorter span, either by design or predation. (2000) collected N. rufipes from carcasses in contact with soil in Oahu city, Hawaii. Soil from the bottom of the holes was not sorted through, but was examined visually for any insect life stages. Table 1: Description and recognition features. Their legs are bright reddish-brown or orange. Adults of C. albiceps appeared on Day 1 in one of the pigs, but only on Day 2 on the other two. Life cycle. They compensate for this by producing large numbers of offspring. (Necrobia rufipes) Appearance.

(b) Necrobia rufipes Necrobia beetle has a world-wide distribution and is known as' Ham Beetle' in America and' Copra Bug' in the Pacific. The adult beetles are 3.5–7.0 millimetres long, convex, straight sided, and the surface has indentations called punctures. Photographs were taken with a NIKON COOLPIX L20 camera and the program Adobe Photoshop CS version 8.0.1. was used to create TIFF files images. 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. Female produces 200–500 eggs. The morphological indexes of larvae were measured in vivo.. Developmental models were established which can be used to estimate PMI min.. A linear discriminant analysis and classifiers for N. rufipes instars were determined.. 2015). It is generally metallic blue in colour but sometimes with a greenish lustre. At ideal temperature of 34°C and 70% Relative Humidity (RH), pupation takes up to 3 days. Necrobia rufipes (De Geer, 1755) (Coleoptera: Cleridae) is an important stored-product species with world-wide distribution. Habits. Commonly feeds on dried copra and other insects that are attracted to moldy food. Riley (1874) gave it the common name of red -legged ham beetle, while in the Pacific Island is known as copra beetle (Froggatt, 1911). Eggs are laid in crevices or on the rough surfaces of a seed. Unless a specific institution is credited, the resources on these pages have been developed by members of the Integrated Pest Management Working Group’s Identification Aids Committee.

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. (Necrobia rufipes) Appearance. The species Necrobia rufipes (De Geer, 1775) is a beetle of the family Cleridae and is commonly called as red-legged ham beetle as well as the copra beetle. 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).
