Comment:
I think bees defintiely home in on eyes. I have seen them zoom in and try to
sting my eyes often enough to believe that the gleam in a mammalian eye
elicits a response from them. Now that I must wear reading glasses, I can say
that glasses (that is, without a veil) is even worse. I gave up wearing a
watch around bees many years ago.
