I dug into the hives a few days ago. We have had a super on top of Virginia's hive for a couple of weeks now, and I fully expected to see the bees building comb and filling it up with nectar. There has been a nectar flow going on for quite a while since the alfalfa has been blooming. Maybe it hasn't been as strong a flow as I thought because when I looked into the super there wasn't much comb.
Another frame with capped honey on the top half and some capped brood in the bottom half. When we first started I worried that I wouldn't be able to tell the difference between capped honey and capped brood. The difference is obvious, isn't it?
