Explanation of Names
Necrobia rufipes (De Geer 1775)
rufipes = 'red-legged'
3.5-7.0 mm
Adult: head, thorax, elytra shiny metallic bluish-green or blackish; underside of abdomen dark blue; legs bright reddish-brown or orange; antennae mainly reddish-brown but with dark brown or black club at tip; sides of thorax and elytra with stiff bristle-like hairs
Larva: body creamy-gray with mottled violet-gray markings on upper surface; head and upper surface of first thoracic segment and last (ninth) abdominal segment with brown hardened plates; 2nd and 3rd thoracic segments also with tiny brownish plates; urogomphi strongly curved upwards
most Nearctic records from sw US - Map (1)(2)(3), native to the Palearctic, now cosmopolitan(4)
found on dried fish, skins and bones of dead animals, and other carrion; also found on museum specimens
summer in the north; most of the year in the south; year-round indoors
dried/salt fish, skins and bones of dead animals, museum specimens, cheese, bacon, dried egg yolk, bones and bone meal, dried figs, palm nut kernels, dried coconut (copra), and guano; also prey on eggs/larvae of some flies, of Dermestes spp., and its own species(5)
Life Cycle
Eggs are laid on the food material; larvae pass through three or four instars; the last instar spins a cocoon in which pupation occurs; life-cycle takes 6 weeks or longer depending on food type and physical conditions. Under optimum conditions, the rate of population increase is about 25 times per month. The adults fly actively and can thus easily disperse to new sources of food.
major pest of copra and materials of animal origin(1); considered a pest in museums containing specimens of vertebrate animals, as well as in places where dried fish is stored
