Re: Different worker sizes?
Yes I'm with 007, if you have a variety of cell sizes you can get different sized bees, although the difference if sometimes not hugely noticeable.
If you have bees that are noticeably smaller, this can also be caused in hives with a lot of varroa. The bees have the nutrition sucked out of them during pupation and end up quite small. One foundress mite will not have this effect, but two or more foundress mites in a cell with one larva can do it.
44 years, been commercial, outfits up to 4000 hives, now 120 hives and 200 nucs as a hobby, selling bees. T (mostly).
