It seems absurd on the face of it that even if a bee got stuck in a
pollen trap - an unlikely event - that she would pull so hard as to
pull her leg or wing off.  Meanwhile, a few bees are dying in the
hive and "undertaker bees" are removing them by pulling on their legs
and wings.  Who could doubt that that is the source of the occasional
bee part loose in the hive?  And underneath all is the pollen drawer
to catch everything which falls (on many but not all trap designs; it
won't be necessary to post that YOUR design does not).  Dan
