I stuffed up again. We just had the hottest day ever on record in Adelaide (or any capital city for that matter)- and it proved too much for two single brood hives. I went to check them today: both destroyed with all combs slumping down and honey dripping out of the entrance. pretty much totally destroyed- 95% bees dead. So sad! Both hives were very strong- single broods- and I was just waiting for a break in the weather to add supers to them. One I had bought back from the brink and requeened a few months ago- the other was a nice swarm I built up. Both painted white with white lids. I am an idiot and should have covered them with shadecloth- up till yesterday they had coped fine with many days over 40c. Both were together at a drier part of Adelaide- and I have a feeling the temps there must have gone beyond 47c. Now there are maybe 500 bees flying around wondering what to do. I am considering moving another hive I have at home and putting it on one of the stands after dark and hoping the lost bees will be accepted.
My own hives at home were all 100% fine- I inspected them this morning and they are great. So this was a big shock.
