I haven't seen any responses to Walt Spears' ([log in to unmask])
speculation:
"Is it possible that the bees could be infested with tracheal mites and
that the mites could be causing a collapse in the thorax from the
inside?"
Did I miss something or were there no takers? The speculation seems
at least possible, no?
