Non-honey bees

Male bees usually don’t take part in any parental care. There is, however, an interesting exception. Males of Ceratina nigrolabiata guard nests when females forage. They defend it against parasites or small predators. What is interesting, males usually don’t stay in one nest forever but they switch between nests every couple of days.
