Should add bees, apiaries, honey, and mead.
Bees as an animal that provide a resource both in the wild and domestically without having to kill them is rarely unique in haz with the exception of sty and should be explored. they could also be implemented similarly to the glow bugs and add similar ambiance to the world.
Apiaries would be used to house domesticated bees and collect honey. Beehives should be for housing wild bees and would be trickier and more dangerous to harvest.
Honey would be used in a variety of new food recipes as well as mead which when warmed could give a buff against cold weather.
