Re: my previous species-identification question, What species is this gray bee? I'm still curious: Are there any recorded/reported cases of either albino Apis mellifera, or at least with substantially different pigmentation/color? Is it possible that only part of a colony gets this trait?
I've been reading a little more, and found a partial answer.
Not sure about albinoes, but Wikipedia lists a few different colors, arguably substantially different:
Under Apis mellifera subsp. ligustica (the Italian honeybee),
- Bright yellow (golden)
- Very pale yellow
Under Apis mellifera caucasia (Caucasian honeybee),
- Dark with brown spots at times
