I know that in the wild, bees tend to make cells of different sizes, even in the same frame, and there are some that believe that natural cell sizes seem to make it easier for bees to fend off pests like varroa mites. I also know that there are small cell foundations that are made in an attempt to try to get the bees back to their natural way of doing things. Also, bees living in warmer climates seem to make smaller cells than those in cooler climates too, which means the diameter of the small cell foundation cells is apparently not appropriate for all cases. These things lead me to ask a couple questions.
Why don't people use blank foundation in their hives and let the bees make cells of varying sizes on their own in the brood frames instead of using small cell foundation? I know that some people do this, but I'm trying to address the necessity of small cell foundation at all. It seems to me that if nature makes healthier bees, in terms of cell sizes at least, we should let bees do what comes naturally to them in those terms.
My other question is, if bees are bred back to making whatever cell size comes naturally to them, does this hinder their ability to use larger cells for things like the frames in honey supers, and does their smaller size limit their honey production or viability as pollenators in any way?
This is just something I am curious about. I'm not sure that I am interested in running out and starting small cell frames any time soon, but I do wonder why the need for small cell foundation unless bees can't be bred back down to the smaller cell size without it for some reason.
