PHOTO 2 of 2: This is the same (what I believe to be Queen) Buff-tailed Bumblebee I posted prior to this photo, just 24 hours later she looked like this, on closer inspection I can see a bug of some sort on her. Her back end was pulsating and she looked really messy. I got very close to her and she was reaching a leg out, eventually she flew off. Please, please can anyone tell me what was happening to her. Is this a case of Bee Mites?
