BUTTERFLY CARTOONS | Cocoon Articles and Butterfly Life Cycle. In the laboratory we studied the taphonomic marks that Necrobia rufipes (Cleridae) can produce. Riley (1874) gave it the common name of red -legged ham beetle, while in the Pacific Island is known as copra beetle (Froggatt, 1911). Adults of C. albiceps appeared on Day 1 in one of the pigs, but only on Day 2 on the other two. Eggs are laid in crevices or on the rough surfaces of a seed. They compensate for this by producing large numbers of offspring. 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). Grows, feeds and pupates within a grain kernel. 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 (De Geer) (Coleoptera: Cleridae), also known as the red-legged ham beetle, is a newly emerging pest of pet food stores, causing apprehension among producers worldwide. Adult is 3–4 mm in length. It is not a beetle which causes a constant drain on the trade, but occasionally becomes extremely abundant and a great cause of loss.

Adult is around 3.5–7 mm in length. Soil from the bottom of the holes was not sorted through, but was examined visually for any insect life stages. The antennae are reddish–brown with a dark brown or black club at the tip. 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). Adult lives up to 3–6 months. The study of the arthropod fauna involved in carcass decomposition is crucial for medicolegal forensic purposes. Shiny green to bluish green in colour with red legs. Commonly feeds on dried copra and other insects that are attracted to mouldy food. 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. Female drills a tiny hole in the grain kernel to lay egg in the cavity. Shalaby et al. 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. Habits. 3.

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. Habits. Life cycle of insect act as precise clocks which starts within few minutes or hours after death. The adult beetles are 3.5–7.0 millimetres long, convex, straight sided, and the surface has indentations called punctures. Howe, R.W., 1953. (2000) collected N. rufipes from carcasses in contact with soil in Oahu city, Hawaii. Females lay up to 30 eggs per day in cracks or crevices of cured fish. Commonly feeds on dried copra and other insects that are attracted to moldy food. Flour Beetle (Tribolium castaneum) Appearance. All the life cycle occurred in the same container. Larva will bore inside the grain to continue growing. (b) Necrobia rufipes Necrobia beetle has a world-wide distribution and is known as' Ham Beetle' in America and' Copra Bug' in the Pacific. life-cycle; treatment options; bibliographic references on the information collected for that particular sheet. (Necrobia Rufipes) Appearance. It is beetle of significance in forensic entomology. This study provides data for PMI min estimation using N. rufipes. Female produces 200–500 eggs. Their legs are bright reddish-brown or orange. Trop.Stored Prod.Inf., 29:21-32 . Necrobia rufipes, did not make effects so quickly on pig tissue, they were observed after a month.

Necrobia rufipes (De Geer) is a beetle, belonging to family Cleridae. Life cycle. The life cycle varies from 36 to 150 days or more de-pending on the types of food and temperature. Concerns about this pest are exacerbated by the lack of information about infestation modalities in pet food, while specific monitoring tools are missing. (Necrobia rufipes) Appearance.
