Summary

Overall nest survivorship rates were comparable to those for diurnal relatives, but rates of cell parasitism for Megalopta (< < 5%) were substantially lower than they are for day-flying relatives, offering some support for the hypothesis that the evolution of nocturnal behaviour enables escape from natural enemies.
