Nicrophorus tomentosus (gold-necked carrion beetle or tomentose burying beetle) is a species of burying beetle that was described by Friedrich Weber in 1801.

Thus, the beetle can locate dead animals (carcass), and then as the name suggests, can bury them. However, unlike other burying beetles, N. tomentosus does not completely bury these brood carcasses. They instead dig a shallow hole under the carcass and cover it with leaf litter. Recognition of these beetles can be distinguished by its black color with orange markings on the wing covers (elytra).

There are several characteristics that differentiate Silphidae from other families. One characteristic is that N. tomentosus is about 11.2–19.0 millimeters in length. It also has a pair of striations on its fifth abdominal tergum. They also have a very large scutellum which can sometimes be as wide as its head. The segments of its antennae are all... Wikipedia →
