Weight is not a good indicator. IMO   I (okay the girls that work for me)
have weighed many pounds of bees   seems pretty much no matter the
condition,  there are right at 3500 bees per pound.   That's the same number
that's been thrown around since the 1950's.

We found the variances in bees per pound to be around 200 bees,  less than
1%   

That is bees fresh from the hive   they will and do loose up to 30% of their
weight while in a swarm or package.  But fresh from the hive the weight is
very consistent for healthy bees.

Is their weight constant?  Does it vary depending on whether the crop and
ventriculus are full or empty?
