Burying beetles or sexton beetles, genus Nicrophorus, are the best-known members of the family Silphidae (carrion beetles). Most of these beetles are black with red markings on the elytra (forewings). Burying beetles are true to their name—they bury the carcasses of small vertebrates such as birds and rodents as a food source for their larvae ...
It is a member of the genus Nicrophorus or sexton beetles, comprising the most common beetles in the family Silphidae. This species is a decomposer feeding on carcasses of small dead animals. N. orbicollis can be used for scientific research both medically and forensically (if the beetle is present in the area).
Silphidae is a family of beetles that are known commonly as large carrion beetles, carrion beetles or burying beetles. There are two subfamilies: Silphinae and Nicrophorinae. Members of Nicrophorinae are sometimes known as burying beetles or sexton beetles. The number of species is relatively small, at around two hundred.
The probability of a beetle guarding is dependent on both the sex ratio and the size of an individual. A larger beetle is more likely to guard than a smaller beetle because smaller beetles require more energy to maintain guarding and are thus unable to compete with larger beetles, so the smaller beetles get little marginal benefit by guarding.
These beetles are scavengers, breeding and living off in rotten carcases. [4] In fact they bury the carcasses of small vertebrates such as birds and mice as a food source for their larvae. In Nicrophorus interruptus both the male and female parents take care of the brood, quite rare behaviour among insects. The prospective parents begin to dig ...
The beetles of N. vespilloides have highly variable body size that ranges from 12–20 mm. [1] They have two conspicuous orange-yellow bands on the elytra. The color of their antennae are completely black. [2] Their orange and black markings serve as a warning sign to avian predators that defends them from attack.
