Another piece to the hive loss puzzle.  In each hive that died, there was a
cluster (?) of bees, about 2 to 3 inches diameter, with their heads in the
combs.  This cluster was in the brood box but was away from any brood
rearing area.  No honey.  No queen.  Just empty, drawn combs.  Usually
close to the edge of the frame.  Covering this cluster there was a minute
quantity of worker bees.  They all died in place.  Would it do any good to
cut out one of the clusters and send it for testing?
 
Thanks.
