Social Behavior
It is difficult to quantify the level and nature of "communication" that takes place among sarcophagid adults, though much is known about the role of pheromones in their reproductive physiologies. An experiment by Girard et al. in the 1970s demonstrated that S. bullata males release the sex pheromone hexanal, which was shown to attract over 65% of the females tested from over long distances. In studies regarding the social behavior of adult female sarcophagids larvipositing on animal remains, it has been suggested that adult females prefer to aggregate with other carrion flies and larviposit on carcasses that already have larvae present. A possible explanation for this selective preference is that an increased number of larvae results in a greater concentration of larval enzymatic secretions on the carrion, aiding in digestion. Sarcophagid larvae are also known to outcompete the larvae of other species and cause their extinction, and occasionally consume the smaller larvae present on animal remains.

Famous quotes containing the words social and/or behavior:
“As blacks, we need not be afraid that encouraging moral development, a conscience and guilt will prevent social action. Black children without the ability to feel a normal amount of guilt will victimize their parents, relatives and community first. They are unlikely to be involved in social action to improve the black community. Their self-centered personalities will cause them to look out for themselves without concern for others, black or white.”
—James P. Comer (20th century)
“There are ... two minimum conditions necessary and sufficient for the existence of a legal system. On the one hand those rules of behavior which are valid according to the system’s ultimate criteria of validity must be generally obeyed, and on the other hand, its rules of recognition specifying the criteria of legal validity and its rules of change and adjudication must be effectively accepted as common public standards of official behavior by its officials.”
—H.L.A. (Herbert Lionel Adolphus)
