Does anyone have a good simple, cheap design for a dead bee trap?

On occasion, I'd like to be able to examine every bee that dies in certain
selected hives.  There are several reasons, but the main one is to watch for
dead queens immediately after introduction -- without opening or disturbing
the hive.

I know that in the case of rejected queens in packages in springtime, that
the dead monarch can often be discovered on the ground immediately below the
entrance board on one sided or the other,  but in summer and with larger
hives, the dead bees are often carried away and leave no trace.
