Where to find bumblebees in late July

In Gardens

My neighbour's Lavendar is buzzing with B terrestris, lapidarius, pascuorum and pratorum, the early bumblebees are still plentiful here. Also a cuckoo bumblebee, R rupestris

In Grassland

The bramble flowers still attract B terrestris 
but the main bumblebee interest is around scabious: B lucorum, 

B terrestris, 

B pratorum

 And these oddities: a cuckoo bumblebee B rupestris?

And a faded B terrestris?
