Silphini

Silphini are distinguished from the related tribe Nicrophorini (burying beetles) by their lack of parental care behavior and different body proportions. Members are generally larger and more robust than typical staphylinid beetles, with elytra that may be abbreviated but usually cover most of the abdomen. The tribe exhibits considerable morphological diversity across genera, with some genera showing flattened body forms (Ablattaria) and others more cylindrical profiles (Thanatophilus).

Worldwide distributed across multiple biogeographic regions including the Australian, Neotropical, Oriental, Palearctic, Nearctic, and Afrotropical regions. Individual genera show distinct regional patterns: Heterotemna is restricted to the Canary Islands and Madeira; Dendroxena occurs in the Palearctic; Oxelytrum is Neotropical.

Carrion feeders; adults and larvae consume decomposing animal matter. Some genera show specialized feeding habits: Dendroxena species have been observed feeding on dry bones and desiccated carcasses rather than fresh carrion.

Decomposers that accelerate breakdown of animal carcasses. Unlike Nicrophorini, Silphini do not exhibit parental care or burial behavior; adults and larvae feed directly on exposed carrion.

Some species are used in forensic entomology to estimate postmortem intervals based on their predictable colonization of human remains. Thanatophilus species in particular have been documented in forensic casework.

• NicrophoriniAlso carrion-associated beetles within Silphinae, but distinguished by parental care behavior, burial of small carcasses, and distinct chemical communication systems including stridulation.
