Answer:
Eu-sociality
Explanation:
The Eu-social term was proposed by Suzanne Batra in 1966. This term describes the nesting behavior of the bees. This is indicating the cooperative behavior in which both males and females bees perform their responsibilities. In these colonies, the cooperation was mus because one group cooperation affects the other group's performance. 
Eu-sociality is the different term from normal social aspects because, in this, one caste at least loses the ability to perform. Eu-sociality found in some insects, mammals, etc. In the colony there are caste differences such as one is queen and others are workers. So that it is useful to understand the functionality of the eu-social organism to think about the collective, living unit. These are the concepts of Eu-sociality.
