Nicrophorinae

Nicrophorinae is a subfamily of carrion beetles, commonly known as burying beetles or sexton beetles. These beetles are primarily known for their remarkable behavior of burying carcasses of small vertebrates, such as birds and rodents, to serve as a food source for their offspring. This process involves a remarkable collaboration between the male and female beetles, who work together to find, prepare, and bury the food source.

The adults of Nicrophorinae are typically medium to large sized beetles, often exhibiting distinctive patterns of orange or red markings on their black bodies. Their antennae are clubbed, which aids in detecting chemical cues from decaying matter. Both males and females possess a strong sense of smell, allowing them to locate carcasses from considerable distances.

The subfamily is divided into several genera, with Nicrophorus being the most well-known and widespread. Members of this subfamily play a crucial role in decomposition and nutrient cycling within ecosystems. Their burying behavior prevents the proliferation of pathogens and makes carrion inaccessible to other scavengers, while also providing a protected environment for their own developing larvae.

Larval development in Nicrophorinae is unique among insects. After hatching, the larvae are not left to fend for themselves. Instead, the parent beetles actively feed and care for them, a form of parental care that is relatively rare in insects. This biparental care ensures a higher survival rate for the young beetles.
