I guess I have drawn a slightly different conclusion... I think bees are drawn to sweat for moisture and salts... I used to wear a braided leather belt and bees were there in abundance landing, sucking, etc. I was only in trouble when turning or wind change direction and an untucked-in shirt tail suddenly covered them... I think they do someting similar for watches be it leather banded or metal....trouble comes when wrist is flexed...skin bunches a bit before the watch band and they get pinched or sense sudden change in position,light,movement, etc.. I don't believe it is reflected light and/or sound as if I am were gloves even ventilated ones while wearing watches...one on each arm...I haven't noticed any problem..... Arm pit and groin area when wearing shorts and a muscle shirt in 90 to 100 degree F heat ARE PRIME targets Cannot comment on rings or ear rings as I don't wear/have any of these.... Perhaps flex watchband holds odors much light a light wool jacket.....wool and bees don't mix...wool jacket, wool socks, wool pants are no no nos! Then again that's how I was dressed when I first encountered a knocked over hive some 15 or 20 years ago....I was fascinated then, discovering queen, brood, workers, and drones....and I still spend as much time as I can observing them today....nothing like napping and/or daydreaming a few feet from the landing board...wondering where they have been, what they are collecting today, etc......One can't describe the cool fragrant breeze my hives produce during a honeyflow.. Back to work.....Hope to see some of you at EAS'95 later this week. Sincerely, [log in to unmask] - Ken Adams, Adams' Apiaries Let me sweeten your day!
