bees evolved for high aspect ratio (>7)cylinders..not low aspect ratio(<1) cuboids
Anyone know the language? if so could you translate? Only know Rustic American English...
tree cavities(bees natural habitat) are very tall and thin...height greater than 7 times the diameter.... hives have the width greater than the height.
when the bees are few in number they can crowd into the top and stay warm. When there is lots of them they spread out and stay the temperature they need.
