Description:

Puzzled by this bees' nest(?). Seems a very odd place - out in the open on bare ground. Bits of wood shreddings and what looks like torn-up polythene along with other fibres. About 5 bees seen in total. In/on the nest, a bee about twice the size of the others. Also some little crater-like structures which seem to contain liquid, and some largeish (~5mm diameter) yellow-gold spherical objects. Would be grateful if anyone can explain what I'm seeing. Thanks!

Could be B. lucorum, the 2 sp

Could be B. lucorum, the 2 sp difficult to id, the craters with liquid are nectar pots &/or for pollen storage, the yellow/gold spheres are the capped cells containing a pupa, depending on time of year they may develop into workers,(Spring/ building nest) drones or Queens for mating ( in a mature nest all 3 being present)
If the nest is exposed it may have been raided by a Badger, which are partial to bee larvae.

Thanks very much....

.... it's really been puzzling me! Badgers do visit this garden, so your last comment fits too. Thanks again!
