After finding a bumble queen in fall 2019, much to my surprise I found another Bumble Queen. She was obvious as she appeared over 1 inch large. I estimated her to be a 'bombus bimaculatus,' based on her markings and wings. There are 9 bumble varieties in the state of Illinois and I have seen the queens of two of them. Here is a link to learn about bumble lifestyles and details.
Enjoy the beauty around you today , it comes in small doses along the street, in the crevasses of the gutter, behind the bushes in your yard.
