I've been observing some behavior that I am having trouble figuring out.
        There are many instances of two workers seeming to become tangled
with each other at the hive entrance.  One will then drag the other onto the
ground where they seem to wrestle in the grass for a few minutes.  Then
either they disengage and both fly away, or one will carry the other off.  I
don't see why two hive mates should be fighting.
        Any ideas what's happening?  Defense from robbers?  Elimination of
sick bees?  Just getting tngled up?
        Thanks you have all been a big help with previous questions.  Sorry
to seem such a "newbee".  Hopefully I'll be in a position to help others
someday soon.
