Beeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeees!
Regarding the sociality of bees, I've learned we have mostly less social bees in the nature in Finland. Pretty much different kinds of hermit bees which do not form colonies.
I'm planning to build an "insect hotel" for different kinds of insects and a large section of it will be reserved for bees.
Somehow it doesn't surprise me that Finland has many solitary bees.
