Excellent timing! The country in the story is fictional, but the climate and fauna are heavily based on midwestern Canada, so I was looking up some of the species native there, to see if maybe Canadian beekeepers (and, by extension, beekeepers in Acarnia) would prefer a native species instead of the global honey bee. This is when I noticed the large number of bumblebees.
I had thought I was good to go. However…
…the main character is specifically trying to sell honey, and does not have a farm set up (at least for a few years). I was starting to get the feeling that bumblebees are excellent pollinators, but break even on honey production. Your comment has confirmed this, and it seems my main character will be focusing on honey bees, instead of bumblebees.
Also, it was rather interesting to learn how one of the most important bumblebee species in agriculture apparently lives underground.
Additionally, 75% of the notes I have so far seem to pertain to the honey bee, specifically, so I seem to have researched this with an outside-in approach, where I started noting behaviors before narrowing it down to the species behind them.
I’m still taking notes on bumblebees, though, because the main character will probably have opportunities to get excited about them at some point. I might also make them her favorite kind of bee, and something she will want to work towards, after getting successes with honey bees. (Similar to how I’m perfectly happy flying an F-16 in a flight-sim, even if the F-22, Extra 300, and Airbus 320 are all missing from the game).
Yeah, a lot of the sources I’m finding say that the properties of honey come from the extremely-low water content. Bees seem to pass honey mouth-to-mouth, taking out fractions of water each time, until (as you say) the water content is too low for the survival of microbes. From there, it’s packed away, and dried even further with wing beats (which is why you can only harvest honey at a specific time, as @Pebblerubble said).
…Huh. I’ve never been able to infodump about something that isn’t one of my special interests before. That’s an interesting feeling. I think I’m getting closer to being able to write this character effectively, lol.
Thanks again to everyone posting info!
