Many wild bees are also specialists, and they will just raise a single generation each year during the appropriate flowering season. They hatch, go wild on their target species, and then lay a batch of eggs for next year. Many wild bee species are correspondingly more efficient than the generalist honey bees; a handful of orchard bees can pollinate an apple orchard faster than a hive of honeybees. Some of these species are pressed more by climate change; at the talk I heard on the subject, these bees have a narrow latitude band they survive in, and as temperatures increase they tend to push up against their northern limit than shift north.
