Where are the bumblebees?

My jade plant is just as gorgeous as it was last year.

Its little flower heads are pink and open. They are  putting out a soft, sweet fragrance. They're just hanging out, ready to be pollinated.

But where are the bumble bees?

Last year it was smothered with them. Bumble bees, being fat and fury, are great pollinators, because they pick up so much pollen.
They were introduced to New Zealand in 1885 to help the spread of red clover in the Canterbury fields of the South Island.
But they have some other gourmet tastes as well, and are eager to fly in and work any other attractive flowers.
My jade plant is the right colour. It's still gorgeous. They loved it last year. So where are they now?

Try this link if you'd like to watch a bumble bee in action (sigh).
