Bumblebees are nowhere to be seen at the moment. They are seriously late

Bumblebee colonies die off in the autumn with only the queen surviving – to hibernate through the winter with eggs and sperm inside her – before starting a new colony the following year – so it’s the queens that we see first, big fat things twice the size of the workers, when they emerge. That happens in March or even as early as February. But in 2013, with April nearing the end of its first week, they’re still hunkered down.
