Good point, and one I have wondered about.

In the smaller members of a normal commercial North American hive -- whether
the small size is a result of genes, malnutrition, or of being raised in a
small cell -- I have not observed a noticably smaller head or thorax.

Is it documented anywhere that bees that are smaller than others of the same
genetic make-up have smaller heads?
