Necrophilus hydrophiloides
Guérin-Méneville, 1834
flat brown scavenger beetle
Necrophilus hydrophiloides is a of in the , commonly known as the flat scavenger . It belongs to a relict lineage of beetles that represent an early-diverging branch of the staphylinoid beetles. The species is found in western North America, where it inhabits moist forest and is associated with carrion and decaying matter.
