Yellow-legged Mining Bee (Andrena fulvipes)
Common Mini-mining Bee (Andrena minutula) perhaps?
In fact
This one has abdomen bands at the anterior of the segments rather than the hind margin. Also a greenish tint.

Very still, caught on the cliff face when the sun went in. But very quickly active as the sun cam out again.
The yellow spot on the abdomen was very visible even when head down in the Dandelion. Fabricius' Nomad Bee (Nomada fabriciana)

It was just at the margin of too cold today. One minute the sun was warm on the eastern side of the pile and there were thousand of bees flying with a glorious active hum. The next minute the clouds came over the temperature dropped and there was silence.
Some were caught out and just stopped out in the open, which gave the opportunity for photography. But they very quickly started up again when the clouds moved on and the sun warmed them up.
