I am not a bee biologist, but I am a hobby beekeeper and I have enjoyed
"listening in" on your network to learn more about my bees and to groan at
your terrible jokes.  Now we have a situation here is Minnesota which perhaps
someone could help with.  One of the members of the MN Hobby Beekeepers Assn.
has harvested some green honey and on one can explain how this could happin.
  In the frame, the cells looked a blue/green color.  In the jar, the honey
first looked olive-colored green, but as the jar sat on the window sill for
several days, it turned a bright kelly green.  Rus Johnson, the author, has
about 150 pounds.  He does not know what plants the bees were visiting when
they brought this crop in.
  Can anyone explain this?
