How bees reproduce?
Again species depending. Female bees only mate once, in fall when the colony dies off. After the mate they overwinter(under bark, mulch, siding, attics, anywhere protected from the frost) then when they emerge the establish a new nest by chewing away wood fibers from raw weathered wood fences or siding, dead tree limbs and etc and combine that with saliva to from the typical paperlike carton for nest construction. The queen produces the nest, builds a few cells and places an egg in each. Meanwhile the queen forages for food, feeds and cares for the larva until pupation occurs. After the first sterile female workers emerge they then take over nest building and brood rearing and the queen stays with the nest. Males and newly produced reproductive queens leave their parent colony during late summer into early fall. They mate or copulate, then the female queens go out to overwinter, the rest of the colonie dies off and it starts all over again.
