NO! Wing index maybee but not by color to bee certainOf course, if you say "NO!" - then perhaps I should bring your advanced knowledge of bee breeding to their attention ?
I am in the starting end of a learning curve and can only :-X burp :-X up what I have learnt so far :-X
BUT I have had hives that have changed colour in mid season with the same queen laying. They started light yellow and ended up dark as night, same number marked and wing clipped queen the whole time.
The queen breeding group I participate in at present time is not interested in measuring the wing index, or counting the hairs on the legs of the bees.
This being said we do not scoff at those that take the time to "NERD" themselves in these issues and we gladly reap the benefits of there labors and in some cases pay them handsomely for there labours that stretch 40years back in time or more.
Reflecting over the great amount work that goes into pedigree and family trees of "queen breeding" or the "breeding of drones" the queens one can buy are sold at bargain price ;)
