Abstract:
Perennial social insects are famous for the extraordinary longevity of their queens. While the lifespan of termite kings matches those of queens, males of social Hymenoptera are usually considered to die after one or a few copulations. While this is true in species with highly synchronized nuptial flights, in others males mate over much longer periods. Male longevity is not correlated with the life span of queens but appears to be adapted to mating opportunities. This is demonstrated by the extreme life span of Cardiocondyla ant males, which monopolize mating with virgin queens over many months. Cardiocondyla offers the opportunity to investigate why male longevity varies even among closely related taxa and how male age affects sperm and offspring quality.
