eusocial
Adjective
Meaning
eusocial (not comparable)
(biology) Of or pertaining to certain social animals' societies (such as those of ants) in which sterile individuals work for reproductive individuals whose genetic endowment they share
Examples
In many eusocial Hymenoptera species, the larvae are fed by female workers.
In the eusocial Hymenoptera, the workers are exclusively female: males (drones) are haploid and develop from unfertilised eggs, while females (both workers and the queen) are diploid and develop from fertilised eggs.
Print. Polygyny in eusocial insects means that some insects living in colonies have not only one queen, but several queens.
That is, presocial animals can display communal living, cooperative care of young, or primitive division of reproductive labor, but they do not display all of the three essential traits of eusocial animals.
The group is called eusocial if, in addition, the group consists of a mother (the queen ) and her daughters ( workers ), with male drones at certain stages.
The most advanced of these are eusocial colonies found among the honey bees, bumblebees, and stingless bees; these are characterised by having cooperative brood care and a division of labour into reproductive and non-reproductive adults.
