(Necrobia Rufipes) Appearance. Necrobia Rufipes has cosmopolitan distribution and was first discovered by a Swedish entomologist by the name Charles De Geer in 1775 (Hinks). Two related species are Necrobia violacea which has all-dark legs and antennae, and Necrobia ruficollis, which has light-coloured bases of the elytra (shoulders). Necrobia rufipes_larva.jpg. Larvae of the red-legged ham beetle, Necrobia rufipes (Fabricius), were the most tolerant life stages when treated with either phosphine or methyl bromide for 48 h exposure at 23°C, whereas eggs of the mold mite, Tyrophagus putrescentiae (Schrank), were slightly more tolerant than mobile stages for both compounds.
