About Necrobia ruficollis (Fabricius, 1775)
Necrobia ruficollis (Fabricius, 1775) measures 4.0–6.5 mm (0.16–0.26 in) in length. Most of its body has a metallic black or dark blue coloration, while its thorax, legs, and the bases of its elytra are reddish brown. This species feeds on dead animal matter, including dried and smoked meats, animal skins, and cheese. It is often found on cadavers that are in later stages of decomposition, which makes it useful for forensic entomology.
