Plus visually for us humans, at least for me, it adds some color and warmth to the area!
And a reminder of a fun day helping to paint Lana and Larry's barn in Dexter, MI!
I mention in the video that bees have a different visual system - looking it up just now it seems they see more along the lines of the blue-green and blue-violet and the ultraviolet spectrum, and maybe some into the yellow-orange too, but not so much in the red and infrared fields.
Interestingly: from the site: http://westmtnapiary.com/Bees_and_color.html
"If deprived of UV light,
bees lose interest in foraging,
and remain in the hive until forced out
by severe food shortages. . "
