said Dr. Nicole Miller-Struttmann, lead author on the new bumble bee study. He says that when cels are 'too small' - he doesn't say what he means by this - an increase of 5% in cell width can give an increase of 1/16 inch in tongue length.If he's on the right lines, then the tongue might get shorter in absolute terms as the cell size decreases. The exterior aspect, as well as its calm and docile behavior are very similar to the ones of the Carniolan Bee. tongues may have done better at diverting that energy into more babies. body length and tongue length on their historic and modern bee specimens.
