I agree with John & Dave C; and because you live in an urban area there is
bound to
be a high diversity of plants, some, e.g. Galanthus spp. & Crocus spp.,
flowering early in the year when pollen shortage in the hive could be
greatest.

And the pollen out of comb has an extraordinarily interesting taste. I tried
some a couple of days ago. The result of the lactic acid fermentation is
very noticeable.

Chris: "David, they have not shredded or dismantled the old comb, they are
cleaning out the remaining few dead bees stuck in the cells and have
polished everything. "

I was astonished at what I found yesterday with the colony I photographed
for the page about remodelling comb at
http://www.heaf.freeuk.com/warre_comb_remodelling.htm on 17 June. Then there
were a fair number of bees but most of the remaining comb was visible.
Yesterday that had all changed and it was comb completely covered with bees
right to the floor. I wish I'd given them the 3rd box on 17 June as the
rapid build up to fill box 2 may have triggered the swarming impulse.
