Confidence: I'm as sure as I can be.
Notes: I'd go for a queen Ruderal Bumblebee for this. It is a social bee - collecting pollen. It can be identified as a ruderatus by the combination of orangey yellow collar and band at rear of thorax. It seems to lack a yellow band on the abdomen, which is typical for this species. Queens like White Dead Nettle. A hortorum would have brighter yellow bands, including on the abdomen, and would probably look fluffier.
