Behavior
N.orbicollis males will search for small bodies of animals such as chipmunks, rabbits, and toads in which to attract a mate. Once a body is located the male will proceed to climb onto the carcass and emit a pheromone to attract a mate. If another male enters the area, the two males will fight to the death and the winner will claim the carcass. Some males have been known to try to attract a mate without providing a carcass. These males will simply emit the pheromones even when they have not located a body. If females are attracted they will mate, but then continue to search for a mate that does have a carcass. Females are more likely to lay eggs fertilized by the most recent mate, so the males that have a carcass are more likely to actually pass on their genes. Once a male attracts a female, the pair will proceed to bury the animal carcass together, equally sharing the workload. If the carcass is too big for one pair, then it is acceptable for multiple pairs to work together to bury the carcass. Eggs are laid and buried very close to the carcass to provide a nearby source of nourishment. Unlike most beetle species, N. orbicollis parents will provide both food and protection for the larvae until pupation. It has also been observed that if one parent is killed the other parent will double up on the feeding and protection duties so the larvae do not suffer. Without parental care the larvae cannot usually survive until the point of pupation.

Famous quotes containing the word behavior:
“This whole business of Trade gives me to pause and think, as it constitutes false relations between men; inasmuch as I am prone to count myself relieved of any responsibility to behave well and nobly to that person who I pay with money, whereas if I had not that commodity, I should be put on my good behavior in all companies, and man would be a benefactor to man, as being himself his only certificate that he had a right to those aids and services which each asked of the other.”
—Ralph Waldo Emerson (1803–1882)
“The type of fig leaf which each culture employs to cover its social taboos offers a twofold description of its morality. It reveals that certain unacknowledged behavior exists and it suggests the form that such behavior takes.”
—Freda Adler (b. 1934)
“School success is not predicted by a child’s fund of facts or a precocious ability to read as much as by emotional and social measures; being self-assured and interested: knowing what kind of behavior is expected and how to rein in the impulse to misbehave; being able to wait, to follow directions, and to turn to teachers for help; and expressing needs while getting along with other children.”
—Daniel Goleman (20th century)
