bee rescue 911
It’s really just common decency, moving a harmless bee out of harms way on a busy sidewalk. I use twigs, leaves, fingers, library card keychains, etc to gently move bees off of the sidewalk so they don’t get stepped on. A professional bee keeper (aka apiarist) once told me that if a bee is on the sidewalk its either taking a rest or dying, so seems reasonable to let them rest on a flower (temporarily or eternally).
