No I don't mean the hive boxes disappeared but all the bees sure did. I thought this summer was going to be a good one with my hive. It was year 2 on my first hive. They had superseded the orignal nuc queen last summer and went into last winter strong. Over wintered well. I fed early due to the warm spring and they built up well. I though the hive would go to 3 deeps for the brood chamber by summer with their growth rate. They seemed to slow a bit early this summer but were doing well, just not as well as I expected with their growth this spring. When things were going good I cut back to checking them once a month (early July). One month they were fine and the next they had all but vanished (early August). No dead bees, no issues with robbing, no moths or any other problems I could see. They just vanished. When I went into the hive I found only a few frames covered with bees. No signs of a laying worker and there was even capped, normal looking, brood. Just not much of it. No signs they attempted to make an emergency queen as if I had rolled her at my last inspection. Just gone. They had even left a full deep of capped honey and numerous frames packed with pollen. So seeing that the end was inevitable I pulled the deep of honey knowing they would start getting robbed soon with their poor numbers. I wanted to get something productive out of the hive and not waste that honey or just feed the wild bees. I consolidated the hive to a single box but their fate was sealed. I put a feeder on but food was clearly not the issue. Really odd. I could understand if they died from something (no dead bees found) or if I should have been feeding and they depleted their stores (had a full deep of honey and pollen) or were overcome by moths but none of that. Nope they just vanished into thin air.
