bumblebees do form colonies with worker bees & drones & brood & a single queen, much like honeybees, but they're much tinier than the ones you'd see honeybees in! sometimes they take over old bird boxes that've been abandoned, and they typically don't even use up all the space there.

they're smaller colonies population-wise, too. there'd be like tens to hundreds of bumblebees in their colonies, compared to tens of thousands of honeybees in their colonies.

idk how to add pictures to comments, but i recommend looking up pictures of them, they're cute! bumblebee cells are just spheres, since they don't have the numbers to require the intense efficiency of the classic honeybee hexagonal cells :D
