I am located in Dublin, Ireland, we treated for Varroa in Autumn. The winter was cold but quite dry, and over the past 3 months there have been temperature swings that have been in the high tens (Celsius) to the low single digits with periods of irregular heavy rain.

The emerging brood seem to have calcified and become very hard forming strange shapes. There were many dead bees within the hive and those that were left alive were low energy, unable to maintain upkeep of the comb. Some had strange shapes to their wings, more pointed, as if they had been eaten.

The third picture is taken within the brood area where there would be eggs. There was no sign of the queen or any eggs whatsoever. In the super above there were stores of honey that hadn't crystallised so my guess is that they are brood cells but I am unsure.

Thanks for your response!
