Interesting discussion, but what about nectar? Well after nectar stops the
bees still are bringing in pollen here in Maine.

We observe here in Maine that in a dearth we have reduced laying and brood
reduction so is it pollen or nectar?

If the nectar stops and brood rearing slows pollen is still needed and does
keep coming in from all those dead flowers.Eventually it also stops but you
would have plenty of impetus to start long lived bees well before pollen
stops coming in. Seems to be better for the bees to get ready for winter
for it to work this way.
