Necrodes
Necrodes is a genus of carrion beetles in the family Silphidae (or Staphylinidae in some classifications), with at least four described species. These beetles are dominant decomposers of large vertebrate carrion in terrestrial habitats, where they compete with blow flies through mixed competition involving both exploitative and interference effects. They exhibit high dispersal ability, with individuals documented traveling over 30 km, and form massive larval aggregations that generate heat through thermogenesis. The genus has significant forensic importance, particularly N. littoralis, which is used as a bio-indicator for estimating post-mortem intervals.
Thanatophilus truncatus
Northern Carrion Beetle, Silky Carrion Beetle
Thanatophilus truncatus is a carrion beetle in the family Silphidae, found across Central and North America. As a member of the genus Thanatophilus, it is associated with decomposing animal matter and plays a role in nutrient cycling. The species was first described by Thomas Say in 1823 and is documented from the southwestern United States through Mexico.
